Engine Performance problem
2000 Chevy Blazer 6 cyl Four Wheel Drive Automatic 160000 miles
My 2000 blazer.4.3l. Was going down road and blazer started losing power. I pushed on the gas and it just bogged out, while losing speed and power. Tried to feather the gas pedal but it eventually stalled. Wouldnt start again. Went back later and started right up. And was able to get it home.(Barely) I quicly put gas pedal to floor and it just bogs and backfires. Went out later to start it, starts right up. When I give it gas.(While parked and driving) it backfires and has a chocking sound to the engine. I get the gas pedal qauter way to floor and it revs. Anymore throttle and it does the afforementioned. When it get warm. About 5 minutes just idling. It stallls and will not start again for 30 min or so. It will idle fine. And doesnt cut out or want to stall until it runs a few min. Then stalls. Ive checked fuel pressure( which is fine) trouble shot the fuel relay cicuits(fine) changed plugs, cleaned and inspected rotor and cap, replaced plug wires, checked all fuses. Cleaned air filter. Replaced fuel relay. Replaced fuel filter also.
have the same problem?
