Engine Performance problem
2003 Chevy Blazer 6 cyl Two Wheel Drive Automatic 170000 miles
----------------------------------------------------------------
I have a 03 blazer 4.3, I think I have a emissions problem, but when the accelerator is pressed to the floor the motor bogs way down but dosent stall the rpm are not going over 3,000. Its to the point that when the car is in gear it strugles to reach 50 mph. Also the motor idles a little lower than normal. I have replaced the fuel and air filter. all the electrical terminals on the motor and emissions control have been cleand. I also pluged into the compputer and read o2 sensor problems but I dont think that is the cause?
