If I blip my throttle off idle I get a slight stumble, under a second but still very noticable. Is this normal? If not, any idea's on how to fix it? Thanks

i used to have the same problem with my efi setup. i fixed it by raising the idle like 100 rpms. with the efi the car wouldnt like to idle at anything under 900 rpms, but with the carb setup i have it set at like 650-700 and its nasty

Check the operation of the MAF and TPS. The TPS is the main one to look at, it basically tells the motor what you want it to do, before the other sensors see it.

Im not getting any codes but i'll have to check the TPS voltage. And I've still got the stock MAF so maybe thats a good reason to upgrade.
