Hey Guys!
I recently rebuilt my 93 tbird sc, and had trouble getting it to run correctly. I found that I (very stupidly) forgot to hook up the main feed line to the vaccuum tree, and that my exhaust manifolds weren't bolted up correctly to the down tubes. (so, I assumed the O2 sensors weren't getting a good reading) When I went fire the car up, it ran really rough(like it was missing), but it didn't smoke and didn't over heat. I had to start the car several times and rev it up to 2,000 and then it would kick up to 3,000 and smooth out. I drove the car around for about two weeks and everything worked great. Then, I took the car to get the exhaust done and when I went to pick her up, the CEL didn't come on with the ignition in the RUN position, but started just fine. I got it home and drove it for two days after that, and one afternoon i was cruising down the street at about 1,000 -1,500 rpm and then the CEL light came on and started running very rough and it accelerated very very slowly. It was hard to get over 20mph. Now if I put the key in the RUN position the CEL sometimes comes on, the Firm Ride light comes on sometimes, and the Seat belt warning light comes on sometimes. It's hardly ever that all three come on at the same time. The car will occationally run correctly, but when I rev it, the rpm's don't fall as quickly as it should. (The rpms drop real slow and kinda hang out at 1,200 for a few seconds and then falls to 700) I really don't know where to start with the car, so I was hoping you guys could lead me in the right direction. Thanks and hope to here from you soon.
P.s.- I had the blocked bored .020 over.
Any questions just let me know.
