Question about 1991 Isuzu Trooper
My 91 isuzu trooper 6 cyl starts up and idles but when the pedal is pressed it bogs down misses backfires. all vac lines are connected
Sounds to me that your cat is plugged. Try unbolting the down pipe from the driverside manifold, and pull it down a bit. Then start and rev it up again. It will be a bit louder, but if it runs fine then you know you have an exhaust plug. I had a car that I got from my brother that did that.
