so ive been looking around the last few days hoping i could find somthing on here but i could. i am getting no cel and no codes. but my car runs good till you give it a lil to much gas then it starts to stumble and ackt like its hitting a rev limiter. has any one els had this proble or know how to fix it.

I would start by checking the spark plugs/spark plug wires/disty cap, correct firing order.

Maybe any leak in the intake between the VAF and the Throttlebody

[ninja_man]

its got new plugs. wires. cap and rotor. and asfar as the intake tube. i put a cold air intake on cuz the old one was f up by the time i put the motor in

Pic of the Cold Air Intake??

If you clamp the clamp on the VAF too tight it will affect the "plunger" thing from moving in and out freely. Happen to me.

sorry i havent got a pic yet. its starting to sleet here so ill try to go get one really fast. i changed the dizzy out thinking that might be it and its still doing it. it feels like fuel cut on a turbo car. im lost. lol

[ninja_man]

so i went out in the cold today and checked the fuel pres. it was 1psi above the losest so i put a new one in thinking that it still wasnt getting enought fuel. i put it in and it still dose the same thing. its almost like im getting to much air and not enought fuel. but my fuel press. is good now. any thought of whats next. could it be a fpr.

so should the 2nd virs open when the car is running and the 1st one never opens. i have tryed a vacum tester on them and thay will both open and close

ur VRIS won't do anything with the idle rev limmiter stuff, but i would recommend checking the timing.... and make sure ur TPS is adjusted right.....
And please do, I thought my timing was correct, so i spent weeks looking at other problems, but the timing wasn't right.
If everything is good, check ur MAF/VAf whatever u call the thing now...

I had a similar problem, i could not go past 4000RPM cuz my timing was way off.... SO try it...

and both VRIS should be closed at idle, and the DE my buddy has with a KL07 ECU they both open at bout 4000RPM...

i checked the time a lil bit ago and it was at about 11. ill go to a junk yard tomorrow and see if thay have a vaf cuz i dont have the money to buy a new one. or is there a way to test them
