ok i originally thought my waterpump exploded and soaked the opti, but i guess it turned out my compressor locked up or whatever, so i got that all taken care of but now the car acts funny, it has a rough idle, and when accelerating from a stop stumbles somewhat, at WOT it misses real bad, thoughts?

 

mine did the same thing, replaced WP and opti, no luck, replaced MAF and a cracked intake elbow, nuh uh......come to find out, plug wires! check them and see if that fixes it, if not, u only spent 60 bux or so on parts u could have used anyway..........or be smart not like me and take it to a dealership and get it scanned!

 

Plug wires most probably. Had the same problem after the first time I changed wires and it turned out one of them had melted to the header and was shorting to ground. You've got to REALLY look some times!
