'05 Astro Cargo van, 125K miles,
I bought this van for work and it has been nothing but a nightmare after another...bought at an auction from a school district near Dallas. Drove it home to Austin and other than AC compressor clutch locking up, it ran fine, Installed new AC compressor and new radiator, tstat, hoses, belts & fan clutch since the radiator started leaking... Also, installed new brakes/rotors on all 4 corners along with rear calipers.
Looked at the Chevy Astro forums for insight to resolve issue(s) below and still haven't been able to fix,
latest symptoms is that it runs ok and then it misses then runs fine for while then it misses again, sometimes worse than others. sometimes check engine/service engine lights come on and off quickly, sometimes they don't. Initially I had no codes while it was doing this until it started missing constantly, it gave me a cylinder 5 misfire. I replaced rotor, cap, spark plugs & wires. Ran fine for a while and it started again. I took it to a mechanic in Houston and he changed the coil pack, fuel/air filters, transmission fluid/filter. 10 miles later it started to miss again on the freeway. When I got home to Austin, I replaced distributor with a new one, no change. replaced fuel pump, no change. Sometimes the abs and brake lights come on while driving and stay on until I turn the van off.
Could it be a wire or the harness? injector(s)? MAF? or the computer?
Thanks.
