Having problems with your GMC Canyon ?
2004 gmc canyon intermittenly starts then dies service engine light is on. on dashboard above odometer says "reduced"
I had the exact problem with my 2004 canyon . Driving fine then die, the DIC would sayReduced power then I would have to wait a minute and it would refire. PROBLEM SOLVED!!! Didn't post until two weeks later to be sure. Replaced Powertrain Control Module 765.00$ had to have the dealer do it because it has to be programmed . Good Luck!!!!!
