What are the general symptoms I should look at if I have a jerky throttle. I just need to know what to clean or change. Basically when I go from no gas, to pressing it, it kinda jolts the car a little.....never driven a car that does this before. I've done regular maintenence, throttle cleaning regularly, cleaned IACV, normal idle.....What could this be?

ttt...why is it that no one likes to respond?

 

have you checked the conditions of the plugs? could be a coil about to go bad but i would think you would have mentioned if you have a cel pop up. do you have 91 or 93 octane? also check the air filter's condition and it would not hurt to run a bottle of quality fuel system cleaner like BG44 or chevron techron.

 

Plugs are new, coils should pop a CEL but I have no codes, I use 91 octance sometimes 93 if gas prices go down but it doesn't matter which gas i get. I have a jim wolf intake, recently re-oiled, and I ran a bottle of Chevron and Redline cleaners not too long ago....

 

what plugs did you use when they were replaced? a litlte bit of the oil from reoiling could have gotten on the maf and causing the stumbling.

 

I bought Denso...replaced no more than 1000 miles ago. About the oil, some other people told me that too so I cleaned the MAF and still the same. FYI, the problem was there also before the plugs were changed and filter reoiled. Also got now motor mounts so that can't be it

 

What did you use to clean the MAF? What you are describing points to a bad MAF. If you over oiled the POP and got a significant amount of oil on the wire in the MAF it may never come off. The wire gets hot and the oil will bake on.

 

Electronics cleaner....this was happening before I re-oiled the filter. And as I understand, everytime you turn off the car, the wire element is supposed to heat up to over 1000 degrees for a short period of time to completely burn off and contaminates on the wire

 

other thoughts.

1) check the ground on the MAF

2) put NGK plugs in...many org members complained how their cars ran without NGK

3) fuel filter
