Engine Mechanical problem
2000 Pontiac Montana 6 cyl Front Wheel Drive Automatic 100000 miles
I have a 2000 Pontiac Montana that is losing power going uphill, hard to start, misfiring and backfiring but only occasionally. Twice the o2 sensor code came up but they also suspect the cat converter they have said that we can't just do the o2 sensors because if it turns out to be the cat convereter they will have to replace EVERYTHING(Including o2) all over again, IS there any way to tell if it is the converter without cutting it out! Is it true I cannot just do the o2's? I cannot afford to get $1,000 worth of work done if it is only the o2's, and NOT the cat, help anyone? This is my only transportation!
have the same problem?
