Question about 1987 Chevrolet Suburban

1 Answer

87 Suburban boggs down, backfires once in awhile, and dies.

87 Suburban starts and has an uneven idle. When the accelerator is pressed initially, it sputters a bit and then appear to be fine. It will die when it is not kept at a higher rpm. It can be restarted for a bit; however, it will eventually not be able to be restarted. After it sits and cools down, it can be restarted to begin the whole process again.

    I removed the fuel line from the carb and cranked the engine. it fed fuel. I am thinking carb, but being a novice makes that just a guess.

I have a1997 suburban 5.7 eng. hesitates and backfires on rapid acceleration.


check that your map sensor has direct (unregulated) vacuum. I don't believe that the purge solenoid can create that kind of problem.

95 chevy 1500 pops and backfires doesn't want to shift into overdrive when cold when it does the truck runs real rough


Have you checked the fuel pressure under a load, low pressure will cause these symptoms. The test port is on the top of the engine in the fuel supply rail to the fuel injectors, the fuel pressure test port looks like a large tire fill valve. You will need a fuel pressure test gauge to do this test (about $20), the pressure must be watched while you accelerate, it should never go down on hard acceleration just up about 6-8 PSI

It sounds like your ignition coil is overheating. Once it cools down it will fire properly until it gets hot again. Replace the ignition coil and you should be all set.
