'93 TA, V8, six speed. 115,000 Mi. I think the catylistic converter element is loose and rattleing around in there. I believe that happed when a spark plug tip came off at 70,000 miles and I drove it too long and it was dumping raw fuel out that cylinder and overheating the cat. I think there may some exhaust leaks around it too.
My current problem is at idle.
- Sometimes won't start unless you give it gas.
- Sometimes won't idle above 500 cold.
- sometimes the idle will swign from low to high and if you don't inerveen, it will eventually die on the low swign.
- Sometime the "check engine" light comes on between 20-40 miles after cold start when you are driving down the road. (50-60).
My thoughts:
- Loose catylicic element is causing wrong signals to engine. (from O2?)
- Air temp wires got chewed through by rodent and was quickly repair with bad solder joints and electrical tape. May be bad connection.
Any ideas?
Thanks John
