I pulled my chevy out of retirement after years of sitting in gargage but fired it up every month and ran it 30 minutes. Replaced a bad fuel pump, changed the fuel filter, took it to shop after a run and had the radiator replaced since it got hot in my first run. Had one (1) leaking injector replaced. Took it out on short runs, ran great came on and died but when I decided to take it on a longer run, 25 miles into it it was running perfect and then SUDDENLY coughed, started missing and then "check engine light" came on and died. Felt like the fuel pump quit. As I sat there with the key on (by mistake) for about 20 minutes, it fired back up (ran rough) and about a mile of so did the same as above. Towed it home and after sitting a couple of days, will fire up and idle just fine but as soon as you press the gas pedal, runs rough (like it's starving for fuel). You can ease off of the gas pedal and then slowly press it and it will clear out and accept fuel and run at higher revs.
again, I put an easy 1000 miles on it before having the one leaking fuel injector replaced but only about 100 miles after the injector replacement before it left me along side the road. Could the ECM have gotten hot enough when I had driven it over heated to have gone bad? Seems like a fuel problem and when it does fire up and idle smoothly the "check engine light" DOES NOT come on. All electrical parts are old in age but new in mileage and usage since it was fully tuned up before retirement.
Thank you for ANY help !
have the same problem?
