I could really use some help as my truck has started to run rough. I recently had the exhaust system replaced as most of it was rusted out. (The truck is twenty years old and from the Midwest rust belt.) I put on a new cat converter with a Flowmaster muffler. The truck ran and sounded great. I was so pleased with how it was running I took it to a trans shop to finally have the trans pan gasket replaced. The trans pan had been leaking for a while and I finally wanted to get it fixed.
Now here's where the problem starts....The minute I started it up and pulled it out of the trans shop I noticed it was running rough. The engine had a slight shake to it and the exhaust note completely changed. it also has a notable loss of power.....
My only conclusion was that something became jarred when they were working on it. I took it to my muffler shop to check for exhaust leaks but was met with negative results.....I also checked for vacuum leaks, once again, nothing. I went out and bought an OBD1 scanner and found no codes.
I am completely stumped and could use some advice! Thanks in advance!
BTW I tried the "slightly block the tailpipe test" and noticed no exhaust leak....
