Do you have a service engine light on? If so the first thing to do would be to check for what codes may be stored.
You can also check for vacuum leaks. A good place for a leak is the TB base gasket. Those start to leak and give a fast idle.
As for the late shifts, just about all you can do is check fluid level. The shifts are computer controled. 93+ trucks have the 4L60E. Not even a TV cable to check adjustment on.
Fix the fast idle and the late shifts issue may go away.

Trouble Code 22 indicates that the Throttle Position Sensor (TPS) is reading abnormally low. TPS volts should be close to 0.42 V at closed throttle and rise smoothly in about 0.02 volt increments to a maximum reading of about 4.85 volts at WOT.
Typical causes for this code include:

1) Maladjusted TPS
2) Defective TPS
3) No +5 volt reference to TPS
4) TPS-return to ECM is shorted to ground or to sensor ground
5) Defective ECM

Good luck, i hope this helps.

check and see if the heater valve is opening. it should be on one of the heater hoses. If it is open make sure that all the air is out of the engine. check and see if both sides of the radiator are the same temp. They should both be the same. If it was working before you changed the stat, then it could be a bad stat

good work, the clicking noise you hear is the blend door trying to move. this door is what controls the temp. the most common reason is the actuator motor is bad but sometimes the door hinge breaks, this hinge slides into actuator and is used to move the door. you will need to locate it on the heater box by locating the noise and then remove the actuator and see if the hinge is broken, i will try to enclose some picture to help you. good day, hope this helps.johnjohn2_142.jpgjohnjohn2_160.gif

All your saying, is that the shop you went to, has no reference
material or data base, to even know what to check on your truck

If you have the factory manuals from Helm.com, you could possibly
figure it out

I won't guess, it is an obd1 system,pre 1996, so it can't be all
that hard

All you can do, is start to research for a shop in your area, that
that is good at everything. I would ask around for a couple weeks,
and then build a relationship for years to come.

It's possible that you have a bad plug or wire. When was the last tune up?

sounds like a sway bar bushing

Hello: Stand in front of the rear axle, facing the back of the truck, scrape off the paint and rust from the axle tube going to the right wheel. It should be stamped on the axle housing. Or you can count the teeth on the ring gear in the differential. (you have to remove the cover to do that.

Well, it could mean that the emergency brake has not been fully released.The ABS system light is on if something has occurred within the ABS system. Something faulty may have happened there, get it checked out!

This trans is computer controled if your gages quit working as well I would start checking fuses and relays. If this doesn't provide a solution let me know and I will get my manual out and go a little deeper.
