Hey guys, having some issues with my '99 Grand Prix N/A.
At idle I hear/feel a missfire and at when I'm at a low RPM load on the engine, it'll buck, sometimes hard, and it'll do it repeatedly until I give it more gas to downshift. I'm assuming the problems are related.
I need to check the codes again and write them down, but I remember having 4 codes, two of which are the cat. I was reading symptoms of the cat, and it sounds a little more severe than the issues I'm having, like complete loss of power etc. Unless this is just the beginning.
I was also reading about EGR today and how that could be gunked up. Any good how tos, or is that pretty straight forward?
I've recently redone the LIM intake gasket and it was running beautifully, new wires/plugs, gaskets, oil/filter, but after about 1k on the new parts, it started acting up. Where to start? Well, besides the codes, I'll try to get those written down.
Thanks guys.
