My car is running REALLY bad, ad idle the engine is shaking like a washing maching and the ride is jerky. Its not the EGR valve because I cleaned it just before the problem started.
Checked the sparks and they seem ok although I don't know how to tell what the problem is. No engine management light.
I did install a K&N panel filter a few weeks ago, it wasn't very oily but maybe it has killed my AMM?
Any help would be great, just to top it off I'm coming down with the flu!
Its an Astra Mk4 with an X18XE1 engine.
