88 S10 Blazer 4.3 stumbles then dies
Hi does anyone have any suggestions, initially it takes a couple of cranks
then it starts & runs fine until idle change, then engine surges then dies. If you try to rev it it bogs then dies. At the lowest point of the surge the timing is retrard quite a bit. No trouble codes from diagnostic and the CHECK ENGINE light isn't on. Sparkplugs & wires okay. Distributor cap, air filter & fuel filter changed not to long ago. I'm going to check fuel pressure next. Any input would be much appreciated! |

You just said what I would check, fuel. if fuel injected, check the injectors and the fuel pump, carburrated, check the mixture. With an issue like this, dont get it professionally done, theyd charge you more than its worth. ask around with friends and get help. -- j bondo Message posted via http://www.carkb.com |
