i bought my envoy and had no problems then when i tried to pull my boat that only weighs about 3000lbs i found out it had no power, engine light was on dealer said the code came back too rich of a full mixture problem was the catalytic converter and of course warrenty did not cover this cost me $500 to fix but was well worth it gained gas mileage also

We bought our car when it was 2 years old with very low miles. When driving or idling the lights would dim. Then it would lose power as I was driving between 30-40 mph. The dealership said it was just because it had not been driven a lot. Well, 2 years later I am still having the same problems and I am at 30,000 miles. Why is there a loss of power and how can it be fixed?

I was pulling a camper over the weekend (weight was 2600lbs, envoy totally capable of pulling it) and I was going up a steep hill and (had it in 3rd) when it started to rev up to 5000rpm (no increase of power) and held there until I put it in drive and let of the gas. Drove the rest of the way home no problem. Stopped at home then went to drop off the camper. After dropping off the camper I got back out on the main road and gave it some gas( about half throttle) and it revved up to 5000rpm (again no power) I let off the gas and felt it shift. Then it just didnt have the pep as it usually does. When I went to get on the highway I floored it on the ramp (slight hill) and I could barely get above 40mph. As i got on the highway I could go over 60 mph. I could tell something was really wrong and pulled over to check the tranny fluid. It was fine, oil was fine. Then my dad drove it and he thinks its the tranny. I thought it was running out of gas (it was almost on E) so I stopped to put gas in it hoping that was it. It wasnt. Then on the way home from the gas station the Service Engine Soon light came on, it drove alittle better( could go over 60mph) but had no power. I went to Advanced to get the code read and it came back with: P0172 System Too Rich (Bank1)
