Hey i was just wondering why my max is so slow. I have a 96 max auto with custom cat back and cold air intake and i ran a 16.2 is that right? And my check engin light is on cause of the knock sensor and also i heard that if the check engin light is on it robs horse power? if so how much horse power?it would be a great help to know this.
thanks

 

Knock sensor isn't your only problem if the CEL is on; KS is a ghost code and doesn't cause the CEL to trip. But you're right, a bad KS causes a loss in power. Check the stickies for how much of a loss.

~THT

 

maybe u need a new tune-up

 

also, do you only use premium gasoline? if not then that robs u of some power

 

i use the lowest that is all i can aford right now

 

Because it's missing 2 cylinders.














HAHAHA just kidding...

 

hey what is a CEL?

 

CEL : Check Engine Light

 

well there ya go... read the stickies, theres a dyno showing how much hp is lost by using anything but premium gasoline, that may also be the reason your cel may be on (it sometimes trips the knock sensor)

 

You can't expect good results with sub-par petro

 

ok you guys im gonna go check and see why my check engine light is on. ill let yall know. thanks for all the help

 

Running 87 octane regular will be a big part of it. Read the stickies about why our cars need premium 91+ octane. Also it is normal to run bad times the first time to the track. You mods also don't give a ton of power either. Get a y pipe and see your times fall after you replace that KS and use premium.

 

Your max is so slow because ur max sucks.....

Jk man....You might be in safe mode depending on what code ur pullin so kinda take it from there....u might get up in the 15's

 

ok lets see i had 7 codes:
11-02 Revolution Sensor
01-03 Engine Coolant Temperature Sensor
02-05 Idle Speed Control
03-04 Knock Sensor
04-01 Intake Air Temp Sensor
11-04 Improper Shifting to Second Gear (Automatic Transmission)
01-02 Mass Air Flow Sensor
-------------
after i reset the only one i had was:
04-01 Intake Air Temp Sensor

i figure my air temp sensor is bad, cuz i used jack with my cold air intake alot(another ebay too-good-to-be-true( i ended up cutting a hole in my inner fender))

well im relieved that my knock sensor isnt back, and im pretty sure its not going to because in a test it turn about 7k. as for some things i have a reason, for example: the improper shifting to 2nd is my fault, and the maf sensor fell off which would cause the maf error. what do you guys think about those other errors that went away. i.e. the first four on the list?? thanks alot guys. my car seems to be a bit quicker---ill test it at the drags this weekend.

 

you should change your ks anyways, has it ever been changed?

 

nooo and it is a pain in the a$$ from the looks of it. ive skimmed a couple of how to guides, but nothin really in depth. ill do it myself and have my dads friend, whos a mechanic help me. also, how much are they?

 

WOW...that's a shizload of codes. Oh my God. I would have shtted myself.

 

lol yeah i just realized that. maaaayn
i only have one now so its cool you know. any tips on where to get a temp and a knock sensor?? thanks

 

Personally, I think you should wait a little bit longer for the reset. I don't believe the ecu checks everything out all the time. Some codes make come back hundreds of miles later. For instance I had an o2 sensor code and some evap codes pop up. I replaced my o2 sensor and reset the ecu and nothing came back. Four hundred miles later I got the evap codes again. Also, I recommend not racing your car around since you can't afford to put the correct gasoline in the car.
Harder you step on the pedal the more gas you burn/waist. I don't know about your max, but mine says on the fuel door to use premium gas ONLY. From what I read, putting in lower grade gasoline can ruin the knock sensor, which would make sense IMO. Since your money is so low that you can't afford an additional 20 cents a gallon I'd recommend looking for a new coolant temp sensor first. Also make sure your cold air intake is installed properly, are the two sensors connected to it (air temp & maf) ?

 

running lower octane gas lowers your gas milage, You can use regular but i bet that you will be going to the gas station alot more.

 

yeah ok you got me there man ill start putting premium in it and see if i can get my hands on some new sensors. also its not because my family is poor or anything its just im 15, i dont have a job, and i have to conserve my money. thanks guys

 

ok sorry i was replying to batxel and my sensors are connected properly

 

i dont know about your max, but mine says "PREMIUM FUEL IS RECOMENDED FOR MAXIMUM PERFORMANCE"

 

i'd also recommend not abusing your car

 

Am I reading this correctly-

Your 15 and your already racing? WoW.

 

hahahah i know. 15. hahahha maaayn. ok as for the *** that said i was abusing my car....ok what you have never turned 7k? do you drive like a granny or what? just becuase your drive your **** slow doesnt mean you have to critcise me

 

1+1=2?

 

+1 dragon, You should Keep your car clean, and start saving now, Then when you get a little older youll thank me for this advise

 

ok baxtel jeez i already said ill start putting premium in it, and then ill get back to you. i looked for those dynos on the different octanes but couldnt find them. can any one give me a link? thanks

ps ninos maxima...saving...thats hard. ill start to save when i run out of little things to buy. lol jk

 

i've got a question, are you manual or automatic?

 

that is a lot of codes... ....alot lol, anyways, Good luck fixin all that stuff..and even tho all u can afford right now is the cheap gas...at least put mid in...thats what I put in mine... I know premium costs alot.

 

automatic(the only reason i typed automatic is because it wouldnt let me post becuuse my orignal message(auto why) was too short, so here i am writing a huge write up on a simple question as to if my car is and auto or standard. hmm its automatic

 

manual maxima's seem to do much better in the 1/4-mile than auto's

and also i don't think i've pushed my max to 7K

 

holy **** im surprised your car moves at all well, you should get all of those problems fixed, get a tune-up, only use 91+ octane in your car, then get back to us on your track times

 

My understanding is that with a faulty knock sensor the car is retarded anyway, so all the premium in the world is simply burned out the tailpipe, even worse that on a usual day.

Peoples' habits sure affect demand. When gas prices first became high, I'd see premium only 11 cents more than regular, because of elasticity of demand. That has really changed. Today, I have seen premium going for as much as 27 cents more than regular. Must be fun to be a gasoline retailer, it's very easy to take advantage of people. It's amazing how for many years premium was exactly 20 cents more than regular, whether regular was $0.769 or $1.499--just shows how artificial that price really is.

 

I really get a twitch in my eye when someone says they can't afford premium gas. Below I did some math of Northern New Jersey gas prices, (these are Exxon/Mobil stations around me. I looked up temple, texas prices and they were around the same. Highest regular 87 octane going at $1.81 and the lowest at $1.60. Let's just say that every fillup, we do about 16 gallons out of the 18.5 :


regular 87 [1.77 * 16gal. = $28.32]

premium 93 [1.99 * 16gal. = $31.84]

difference of $3.52

Say for some miracle prices were $1.60 [1.60 * 16gal. = $25.60] . Even with a ridiculous price of $1.60, if you just shed the extra $5, you can fill with premium. You spend more than $5 easily on food in one sitting. Just let this be something to make you fill up with the good stuff after you get everything fixed. I'm a college student and I work a crappy job, but I will skip lunch a couple days of the week, knowing that it will cover the 'extra' money paid on gas. Good luck. and USE PREMIUM.

 

i understand that. but like i have said before, using anything less than 91 octane sometimes trips off the knocks sensor. it has happened to me before in my old ecm

 

how in the heck do you drive around at the age of 15 and get into tracks and not get caught? i wish i coulda did that

 

^^^^ i was just about to ask the same question, I never could run at my local track tell last summer. And driving at 15 with out a parent ?? I mean I use to do it but I never left my subdivision, also hey how about you get a working permint and get a little part time job. You could work on the weekends or once or twice a week. Atleast then you would have some money

 

Automatic. I'd use Premium gas for now on, yeah it's expensive but if you're planning on speeding then I'd use what's recommended. Also someone said you should take their advice on saving your money. You should, dont bother racing and spending money on mods. Save your money for a couple years and then you'll be happy to find plenty of mods that you can afford.
