Car jerking around

[Michael Spina]

My names Michael, I OWN A 1998 mcv20r TOYOTA Camry (3.0L V6).

I have an issue where by the car will be driving and as soon as I descend down a hill, it will start to ***** around, feels like its trying to fuel cut (I know its not though, just feels like it), then when I pull up at the lights it feels like its trying to stall.

I have been informed it could be O2 sensors, Cracked on-board computer board, MAF sensor as well as various other things. I have found that if it does it, I pop the bonnet and tap the EGR Valve with a screw driver it will stop it and run normally, yet I have replaced the EGR valve 4 times. Anyone experienced the same problem or know what it might be?

Any help would be greatly appreciated

Could possibly be a dirty idle air control valve(IACV), couldn't hurt to give it a clean.

Thanks Trent, I have been informed to clean it out, will give it a go. Thanks again

Also, should it affect the car when I cold start it in the mornings?
Because the car starts fine on a cold motor, it just does this when its been driving (on a warm engine).

Yep, idle control valve. If not fix simmental your car!
