so i have some hesitating at low rpms when cold (2000) usually when i hold it at 2000 it wobbles slightly then wobbles down to to 1600 rpms but if i mash on the peddle it revs normally same when im driving when cold i can feel hesitation when i softly take off but if i take off with some force its fine or better at least until it warms up, so i know there are alot of posts on here about bad mafs and simular problems but every one i read that is even close to mine they talk about the car stalling or the rpms are above 2500rpm and it starts messing up, so to me its a different situation the only syptoms im having is hard starting when cold, unless its primed twice( which to me means to much air not enough gas hence it starts when there more gas givin to it , and the hesitation while driving or revving the car in park at 2000ish rpms ( its a litlle lower when driving it just feels like a miss when driving but its not a miss) like i said its fine when its warm, i spray tb cleaner all around the motor when it was cold and no increase in rpms so im really leaning towards my maf but i dont want to spend 300 and have it not be the problem and then i cant return it!!! sooo, i need someone to chime in saying they had the same issues, i have replaced fuel catch(filter), plugs ,coolant temp sensor, my coils are original but there good for sure( plus i dont think a miss would act up only at a certain rpm it would be constant when im driving at high speeds hot or cold its perfectly fine wich also leads me to think its not an intake leak please someone help

 

Try running a can of seafoam in your next full tank of gas to clean up the injectors

 

I'm from vancouver in canada, we don't have sea foam here. Ill try some other stuff, though I don't think that's it because it only happens when its cold a dirty injector would be a consistant problem??? Wouldn't it??? Ill try though and keep you posted thanks for the advice!!!

 

I'm with ghost.possibly fuel pump going. Dirty injectors. Or the like.



With my maf I just seemed to have a dead spot. It was semi consistent not just cold start related.

 

My 2003 maxima lately from week or so is sucking up the gas and gas mileage is really gone seriously low from last week. Will the can of seafoam fix the problem?. There is no check engine light. can the really cold weather affect the gas mileage?
