I think my car needs a complete exhaust system as I've put muffler cement on it but its pretty bad and needs to be replaced could this have triggered this any help would be greatly appericated as always

Check your alternator and battery.

Take battery voltage when not running, it should be 12.6 or so.
Take battery voltage when engine running, it should be 14.1 or so.
If battery voltage is the same or less (such as 12.1) than when the engine is off, it's the alternator (the voltage regulator).

Give that a try, it doesn't cost anything, and isn't too tricky to attend to if you have a PD.

I've had the same problem, replaced battery with proper sized unit and it fixed the issues.

Alright I'll look into that I've had the same battery for a year now and it was the proper size for the car. I could be the alternator I will check that today thank you. Could it be my glow plug harness as I had switched that last thursday

Didn't you just have hitch wiring installed? I've only seen that screwed up 9 out of 10 times.

Hey it was the altenator it was over charging thanks to everyone for the help
