Loosing power

[Molson02536]

I tried the paperclip, & it blinks. I SUCK @ morris code! is there not a code reader/scanner that has a digital face that the code pops up on?

There is and here is the a link that will give you the information you need to get fancy as to getting a full reading. But you are going to need a ALDL cable for your laptop and the program.

Good luck and keep us posted.

I was talking to some others about the problems with this truck. They said to unplug the connector at the tail of the transmission & drive to see if problems still persist. why would that make such a big differance on how it starts, runs & drives? It's like a new truck! And is that sensor bad?

Hope this helps. I pulled it straight from Alldata.

Set timing under the following conditions:

* Normal operating temperature.
* Air cleaner installed.
* A/C "OFF."
* Transmission in neutral.
* Disconnect SET TIMING connector.

The location of the set timing connector is inside the cab where the heater box and the carpet meet on the passenger side floor. Pull carpet back to expose the single wire and connectors on the outside of the control module harness. The wire colors are tan with a black stripe. DO NOT disconnect 4 wire connector at distributor. (connector is sometimes found hanging right in front of the blower motor)

Connect timing light and adjust as necessary by loosening hold down bolt and rotating distributor. Tighten hold down and recheck the timing. Stop the engine and connect SET TIMING connector. Clear control module trouble code by disconnecting control module power source. With engine at operating temperature, drive vehicle at part throttle with moderate acceleration and decelerate to idle condition. This will "teach" the control module and return the engine to normal performance.

Set base timing from 0 BTDC (factory spec) up to around 4 to 8 BTDC or so. Higher you go more likely it is to ping. Snug down distributor, re-check, shut engine off, reconnect bypass wire. Remember to always test drive after you make any adjustments to get the most out of your engine.

Check all your vacuum lines and replace any that are damaged.

I did finally find the SET TIMING connector. it was wrapped up in tape, hanging right in front of the blower motor. When i Clear control module trouble code by disconnecting control module power source, can i just un hook the battery for a few minutes?

I don't quit under stand what the SET TIMING connector does, but when i plugged it in and drove it it ran bad, unplugged it, been driving it no problems. With SET TIMING connector plugged in the engine loads up, put timing light on it, it was 20 degrees off, i might be exagerating a little but it was bad. unplugged, no smoke no problems. If anyone is still reviewing this can you give me a heads up on that SET TIMING connector.
