For your year 21 should be the TPS, and 66 should be Low refigerant..... Need someone with a 93 service manual to verify

If you had a knock sensor code it would be a code 43
The EST( Electronic Spark Timming ) Circuit would be a code 42...
I just want someone with a 93 Service manual to verify so that we are 100% sure...

A bad TPS can make the car do some not so happy things, and affecting the idle is one of them...
