the other day when i was leaving work i went to start up my car, it idled the high idle it usually does when its real cold, but when i was driving away, the very second i had the clutch out all the way the car started jumping real bad and giving it more gas would make it loose all power. i was thinking this was water in gas or frozen gas lines so i put in the "heet" stuff, and it got better right away, then about 15 mins later it started screwing up again, what could this be?

 

water in the gas, Bad gas, or ?

 

maybe maf

youll have to give us a better idea of what its doing whenits doing it

is it only when oyu push the clutch out only when you have your foot on the gas only when its in gear that kind of stuff

also what year is your max and how many miles

 

its a 91 maxima. i found out its not just when i let out the clutch, sometimes out of no where itll just run like crap. itll ping, wants to die when i give it gas, hard to get near or above 3000rpms in neutral, and impossible to even move the car without it dying on me. but itll just go away after a while and then come back. it just started this winter during the cold and when i was on empty. i replaced the fuel filter tonight and tried blowing through the old one which i replaced last summer, and that seemed to be a little clogged, hopefully thats my problem...

 

118,000 miles

 

My uncles Volvo had the same problem and it was his fuel pump dying. Once he changed it the problem went away for good.

 

ok this sucks big ***** i am having the same proablem coming back for target i was on i-80 and when i pulled into 2nd gear it started to lose all power and not go any where then 2 mins later it was working fine . then another 3 mins later same problem i think its the fuel pump as well ...


should i change it im on a half a tank or you think its the water in the gas problem let me know

what do you guys think about this pump



http://cgi.ebay.com/ebaymotors/ws/eB...tem=2455983998

 

try using iso-heet first..its less than $1 a bottle..I personally would not waste money on regular heet, as ethyl/methyl alcohol removes an insignificant ammount of water..iso-heet is mostly isopropyl alcohol, which removes a LOT more water..also, if the gas is bad or just too low of an octane level, that might perhaps cause it..try an octane booster..those 2 are solutions that are cheaper than a fuel pump and may atleast get you through to better weather to check more in-depth

 

He also shows it for the dodge stealth, RX7, MX-6, CRX,accord, civic among others.
So basically you are looking at a universal pump.

 

do you think the pump is any good

 

the pump is probably fine, if you don't mind cutting wires and making other adaptions for it to fit and function.

 

i have a 255lph walbro pump in my 92 for about 2 months with out problems

1 if you deside to buy it make sure you find out if its the high or low pressure. if its the high pressure pump you will run rich with oout an ajustable FPR

2 yes i had to splice the 2 wires for the pump and the walbro pump is about 1/2 the size of the stocker but it comes with all needed installation accesories to make it fit all hoses hook right up

 

ok heres an up date i put costal anitfreze for gas and it stoped doing the shake slug dance lol!!!!!! any way so then i hooked up my friends snapon computer and i got 2 codes

1 was detantion sensor or cuirtcit is bad (knock sensor??)

2 L-oxygen sensor bad... also is this the on the y pipe (i just repaced it


we reset the computer form the snapon system and tomorrow i will check agine it it has the same problems i do think the knock sensor is bad i feel some tomes losts of power and some times not as much for no reson .

thanks guys

 

any opions

 

it also only seeems to do this when it is wet/slushy outside

 

do you have a cold air intake

 

This was the first problem mine had when I got it. Some days it ran great, the next it couldn't get out of it's own way! When I checked the computer code I got the same two. Eventually, it got to where it just shut down at random. I had a bad coil (actually 2). The heat from in the head cracked the insulator on the coil. This causes the plug to misfire. That sets off the knock sensor code. I also had a fuel pump relay going bad. I was told a million times that they either work or don't. Well, mine worked sometimes. Thats the honest, parts man stumping, TRUTH! That is in the trunk under the trunk latch, little Green box.

That is what I did to fix mine. You can check the coils for cracks by taking them out and looking at them

 

no but i have a highly cut up air box, to let in more air

 

my dad suggests replacing the distributer cap, does that sound worth a try?
