My 94 T/A had a tune up around June and now it's starting to run choppy again. Well after the opti was put in the car drank decent amout of water and then I let it sit there for few days and fired it and it worked fine. Recently it started running choppy when the engine would heat up to 210. But then agian it would do it sometimes not all the times. Today comin home I broke her loose and did about 80mph and then when I was at a light I had the break pushed in and the ran started moving up and the rpm started jumping around. Then the second time it went up to 1500rpm and then went back down. I am guess it's the Opti spark what do you guys think.

Also the second second problem I having it the shifter. It's a A4 with about 115K on it. Well when i press the brake and shift it, some times it's kinda hard to **** it and then again when i put it on park the push rod the little swtch doesn't come up all the way and when that happenes i gotta take a niddle nose and pull it up. I did put some WD40 in there and it seemed to help and then it did it again and the second time it didn't do it. What you guys think. Please help you thank you very much.

 

Come on guys...help me out here please...I don't know what to do...the car runs fine when it about 180 and starts running choppy as hell around 210...what you guys think...the egr, thermostate and the plugs and wire were replaced recently. Help me out please...

 

My car was running really choppy at low rpms and would really hesitate when I really hit the gas at low rpms. Turned out one of the plug wires was shorting out. Replaced the plug wires and car ran fine afterward.
