I have a 96 2.4L Z24, it's chugging really badly, and I've tried replacing the spark plugs and putting injector cleaner in the gas. Im not sure what to try next. The check engine light is on, Im getting it checked tomorrow, but in the meantime......wow, it's shaking bad. I thought about checking the EGR valve, but unsure if this could be the issue. Any suggestions?

What code did you get?

Actually, I took it to a Chevy dealer and it turned out to be a vacuum hose sensor - after I went to all the trouble of changing the spark plugs - that was a huge pain! I dont think I had the strength to put the valve cover back on - somehow I managed. Thanks though!
