My 2000 chevy express 1500 with 110,000 miles, started hesitating on acceleration 4 days ago. In the past 4 days it steadily got worse until now when it won't go above 30mph. It runs fine at idle, and will run normal when cold. But after 5 minutes of running it will backfire and sputter if I press the pedal more than a fraction of an inch.
The fuel pump was replaced about 4 months ago, and the transmission was replaced about 3 weeks ago. I have replaced the spark plugs, distributor cap and rotor.
have the same problem?
