My son was having a similar problem. Turned out to be the ignition control module located inside the distributor cap. You can take it out with a phillips screwdriver and have it checked at OReillys.

check your timing, check that your ignition pick up coil is good. also check your fuel pressure. and check for any vacuum leaks. double check your coolant temp sensor to the ecm it tells the ecm what temp it is and the ecm adjusts the fuel amount accordingly.

I have a problem with my 1989 chevy pickup. When i bought it it ran good but had problems going in to passing gear. Now a bigger problem exists, when you start it it will idle for about 10 minutes and...

A common problem on these trucks with the symtoms you described is the gasket under the throttle body. It's about a $2 part. Ther's only three bolts that hold the throttle body on. You can leave everything attached to it and just lift it up about a quarter inch, slide the old gasket out, slide the new one in. It's worth a try.

Will not idle

Hi lanzmick,

A few questions:
  • Is it difficult to start too? Need to keep your foot on the pedal?
  • Carb or FI?
  • Did this just start happening? Gradually? Correspond with some other event or part replacement?
  • I believe your vehicle has an option for OBDII diagnostics. If so, stop by an auto parts store and ask if they can do a code reading. Most will do it at no cost. This will hopefully give a definitive reason for the problems.
In the meantime, check for vacuum leaks. Inspect for loose or cracked hoses.
I know this can be difficult, but try keeping it running while listening for a sucking sound that isn't the intake.

If it's carb'ed, check the choke and its associated linkages.

Check the timing.

Get back to me with the results, we can pick up from there.
