I have a 1997 chevy silverado and am having misfires on cylinders 4,6,3,5. I replaced plugs,wires,cap rotor and spider injector unit,i have also pulled the distributor to make sure the gear and shaft were ok.
JA: How many miles are on the car? Is it a steady misfire? Or random?
Customer: 251,000 miles,it is a steady misfire and i noticed that i do have to press the gas pedal a bit to get it to start,the fuel pressure readins are all good which is weird.
JA: What is the model of your '97 Chevy?
