chances are you need to replace the cable or the gear at the end of the cable or both.

SOURCE: 1990 CHEVROLET K1500 350 MISSES AFTER WARM

My first thought for a solution of your problem is plug wires. You have replaced some common problem areas for this situation but the plug wires are the most susceptible for causing a miss after engine is warmed up. Try replacing the spark plug wires and let me know what happens.

The crank angle sensor maybe bad. It sends a signal to the computer so the spark plugs fire up.

HOW TO CHANGE AN EVAPORATOR ON A 1989 DODGE ARIES


To replace the AC Evaporator core you must remove the dash from the car, a very complicated job, a factory manual is not an option here. You can access the factory manuals for a fee at this site www.alldatadiy.com, it is what shops use. The job takes about 12 hours at home.

1989 chevy hearter coral needs holes..how to repair?


In the engine bay on the passenger side against the firewall. Follow that which should lead to 2 nipple fittings or 2 tubes where the hoses connect to the engine. Replace the hoses when you replace the heater core. If you try to replace the hoses later, you may break the fittings at the heater core because they have minimal flexibility.**Please rate me on this answer**

2000 chevy cavalier having coolant leak. Found a small rubber elbow hose about 2 and a half inches comming out of the firewall leaking coolant while engine is running and dripping while engine has stopped...


That hose is the drain hose for the air conditioner evaporator. If it is leaking coolant, there's a good chance that your heater core is leaking, as it is in the same 'box' that the air conditioner evaporator is in. You'll need to replace the heater core.

How to replace heater core on a 1989 Chev. 1500 (350)


Start by draining the coolant, disconnect dash board wiring harness from pcm behind kick panels, disconnect eye shaft, unbolt dashboard and remove dash. (Remember to tape steering wheel in place as it might have a clock spring). You might have to remove some trim panel on top of dash or cluster from dashboard to gain access to retaing bolts, disconnect heater hoses from heater core in engine compartment and remove heater core, reverse install.
