hello,
I recently replaced my entire exhaust system (cat & all) on my 92 ford f150 (6 cyl). Upon a test run, I noticed that the car, on acceleration, sputters and rumbles profusely (1st gear seems ok, 2nd &
3rd are problemmatic). Could this be a result of something with the exhaust system? It was ok prior to the change though it has been sitting idle outside for several months now as well.thx
