I need to know if anyone have had the same problems as I do?

1- my overhead console started to go berserk by showing a temperature of 120 degrees in the middle of winter.
2- my digital odometer goes off most of the time.
3- I had two spark plug coils burn out
4-my "service engine soon" indicator won't go off
5- my headlights waver in intensity, same as my cab lights.

When I get a diagnostic done on the truck it shows that I need a new manifold????

I don't think its the alternator. I had it checked and it was OK

if anybody knows whats going on it would be great if you could let me know

 

Did all this stuff happen all at once? Or did one thing happen one month, and before fixing it, the next happened, and so on? If it's the first....I'd suspect a ground. If it's the latter, could very well be that it's all a coincidence that it's all broken at the same time. Either way, check your grounds (battery, engine, frame, body, and dash). I'd also do a load test on your battery. Just my 2 cents......

 

You could have a bad ECM for all that to occur at once
