Question about 1999 GMC Suburban
I have a GMC Suburban 1500 SLT that dies when it is run for more than 15 miles. We just replaced the catalytic converters, as this appeared to be the issue. When you would accelerate the vehicle, there would be no response. After replacing the converters, this disappeared and the truck ran great. I don't know where to look for the problem. The truck will not run, once dead, for hours after it dies.
Ignition module have a parts store test it. It has 6 stages to be tested
