more info

I just talked to a buddy that works at the dealer and he wants me to try something. He thingks the coil might be breaking down under heavy load, so I'm going to tape the trigger on a timming light and drive down thew road and see if it blinks constant or not . What do you guys think

 

[jermil01]

How are you going to see if it blinks under the hood and drive down the road all at the same time???:brownbag

 

[bigblackbitch]

duh

well lets think about it...... if I am going to tape the trigger on the gun where do you think I would out it under the hood ........NO I wouldtape it to the windshield so i can see . so now that that is cleared up .:twak

Take the sensor out of the rear diff and clean it off. If there is excessive metal on it, your tone ring may be bad.

The tach gets it's RPM signal from the TFI module. I had a tach not working right on my '87, put a new TFI in it, everything fixed.

Would you guys think of something already

I was told we have people of knowledge on this site and all I have heard is crap Give me some good ideas. I think we have a driveablity problem because now the truck just sitting still feels like it has a miss . If swapping modules is all its going to take then good , but wasted money right now would not be a good thing . It dosen't throw any codes that is what is bothering me the most , for once I want the little fricking light to go on. It is just a little miss but once you try to put some real power down thats when it really starts to buck, chug aimlessly drive like chit. I know you guys have some ideas , dont be shy lets hear it. Thanks for listing to this bitch session, Ryan

 

[Broncobob]
