That sounds to me like you have a bad ignition key switch. for it to read the chip in the key the switch needs to be able to recognize it. Hope this helps getting you going again :o) Jesus loves you John 3:16-17 (KJV)

Thermostat stuck open .

Remove battery cables and clean battery terminals, reattach cable and tighten.

210-230 degrees usually .

There is no simple solution for this problem. A mechanic will have to see the linkage and cable to diagnose the problem and affect repairs. Sorry.

First run a fault code test on the engine control module to make sure the problem is not in the electronics, if all is ok then the transmission is starting to fail.

At idle? At 60 mph? In drive or park?

It could be, best thing to do is start your car and with radio on, but volume on low, listen to the passenger rear speaker for the noise you are talking about.

If it is not starting you need to check the fuel delivery system, along with the ignition system for spark. The exhaust system or pipe has nothing to do with vehicle engine startup.

Most likely throttle position sensor is defective.

under the heads on the block

Idle speed on fuel injected engines is controlled by the idle air motor. Yours may be dirty, EGR dirty, vacuum leaks, MAF dirty, tune up issues. DON'T turn the screw which controls the throttle blade closed position, but do check that the blade is clean and not sticking open, as this prevents the IAC from doing its job. Bad coolant temp sensor or O2 sensor can affect idle quality also.

unscrew it and screw in new one
