Celica Forums General Discussion Engine and Performance HELP WITH IDLE PROBLEMS

the problem is say when im down shifting from third to second to stop as soon as i take it out of second gear my car seems to hesitate like nearly stall even if my car is still rolling (slowing down)like i was just watching my rpm needle bounce up and down well below 1000 rpm.

im not sure if its my MAF sensor i just recently cleaned and pre oiled my k&n flat panel filter

any help is appreciated

clean the MAF sensor and iacv

my car used to have the same problem. even when it was idling, when you push the accelerator the Rev meter will go down first for a while before it accelerate.

i got the MAF replaced and the car ran like mad now, all solved.

your maf is a very expencive and delicate part. I would highly advise not cleaning it unless there was a problem with it, because you probably messed it up when you cleaned it. see if you can swop it out and see how your car runs with a new maf and then leave it alone.
