So I have an 88Gt and it was running rich and getting 11 mpg and it would run real choppy under 2k rpms and not accelerate until it hit the the 2k. So I did some research and figured it might be the ect sensor, so I went ahead and replaced it and cleaned the throttle body while I was there. Now it's worse, its alot choppier I don't know if its choking or running lean. Any Ideas? Thanks in advance.
