Okay guys, I've exhausted my ideas on this one! Whenever I start my car after sitting for about 2 hrs, there's a huge dead spot in my rpm's where if I give it any fuel it falls flat on it's face. Only if I ease into it though. If I give it a quick rap it's not very noticable at all, but it's still there! After warming up it seems to dissapear, but even then there's a varience in my rpms. They go up then down, then up, then down. It's not throwing a code, it has new plugs, wires, and O2 sensor. I haven't changed out my injectors, but I've checked them and they all seem to be firing normal. Any other ideas?

 

1.bad tps [throttle position sensor]

2. bad/dirty maf [mass air flow sensor]

3. Dirty connectors on both

 

check to see if it's throttle position related.
see if it always happens at the same pedal position

 

anyone think seafoam will help???

 

Hello guys, for some reason I cannot post a topic so I came into the closest topic related to my 1992 Maxima.
Here goes,

When I accelerate my RPM's drop like crazy and it revs my car with the RPM's flucuating. If I leave my foot on the gas while this is happening it will cause me to stall(most of the time). This does happen at random, mainly when its really cold out and when I am merging on the highway.

I have went to 2(two) mechanics and they both told me that they couldnt figure out what was wrong with the car. they saw what was happening but couldnt do anything about it. There were no error codes read either.

The 1st mechanic fixed the Fuel injector that was bad. That fixed another problem that occured at the same time as this happened. I have been using 93 octane gas as well. I just changed my plugs and my fuel filter. The car will jerk front to back while driving.

Can anyone assist me in the right direction?

Thanks in advance.
Ed

 

coil packs

 

you have the 1992 SE right with the DOHC motor???

 

Yes I have the 1992 Se with the DOHC Motor.

 

i guess coil packs also!

 

Doesnt the coil packs either work or dont work. Not just work sometimes?

 

sometimes they work right, sometimes not at all and sometimes they don't work right

 

sometimes they crap out on you when they are stressed out, or like then you put stress on the motor, EXAMPLE: when you step on the gas pedal to move the car.. other times like when idling, they may be fine

 

Thanks for the advise. It seems like my car now stalls when I am idling at a traffic light. Are these hard to replace? How much do these generally cost. thanks in advance.

 

they are not hard to replace at all, but they are expensive as hell!

 

VE coils are only like $70 ea

 

$70
x $6
_______
$420 !!!!!!!!!!

 

I wouldn't replace all 6 at once.

you guys have answers for everything....

 

thanks a lot guys. I will check this out and let you all know what happens.

 

my car seems to now be stalling when I am idling at a light. Would this be a result in the same issue with the possible coil packs problem?

 

could be, but more specific information is needed
