Question about 2002 GMC Envoy
My 2002 GMC Envoy is loosing power. It struggles to get up hills and now needs to downshift on hills it easily climbed before. It also takes about 3-4 seconds of cranking to start instead of the previous 1/2 second.
Just got my envoy back from the shop . it was loosing power strugling up hills,the thought it was the throtle body but it was infact the cat/conv,causing the throtle body to open up.yes it fixed the prob,but the converter aint cheep,go with factory part not aftermarket.the after market causes u more problems in long run

Two things come to mind
1 fuel injectors are gummed up. get some berrymans chemtool and put it in the tank do it twice.
2 I had a ford ranger that had the same symptoms after warping two heads the mechanic discovered that the catayitic converter was blocked
