idle problems

[CorollaINC]

I did a recent spark plug change on my car ( 91 corolla GTS 4age) and i have been experiencing some weird idiling problems, when im driving the rpm meter bogs at 3 or 4000 down about 500 rpms and does this untill i punch it hard. i need to know what tha hell is goin on.

Hi!

Well, check the plugs! Sometimes, you can run on a brand new spark plugs with fault... also check spark plug cables. And maybe you have to do a little engine tune-up... I've had similar problems when I've changed plugs... but problem gone after a few days (the day I wanted to go to my mechanic )

i say gasket...i had the same problem and when i fixed the gasket to the manifold it felt that it was new Rolla again...

it could be a cracked manifold

the rolla likes to crack
