1999 Gmc Suburban no power after half throttle have to start vehicle with starting fl
So i have an issue with my 1999 suburban that is hard to get an answer on
So the burb has had this issue since ive owned it I have to use starting fluid to start it when its cold it has no power when accelerating past 30% backfires back thru the exhaust so far i have replaced the following parts used intake assembly off of a running 5.7l new direct fit cat and new 02s new fuel pump , not sure if filter also was? good working , maf , air temp sensor and igniter. im thinking the engine is running to lean or too rich which would explain the no start with out starting fluid (lean) , or the engine is running too rich and backfiring thru the throttle body . not sure if ineed to replace the spiders or not? |
