Bought the car used 5 months ago. Seems to have been running good other than recently has been idling high and RPMs slow to go down, will stay up at 3k while shifting (manual trans). Drove somewhere and then would crank but not start after being shut off. Going down the list in the Chilton's manual. Replaced fuel filter and gas pressure to fuel rail now much better. Don't know anywhere further along where I could check fuel. Replaced one bad spark plug wire, all wires and both coil packs pass ohm checks, now spark verified at all 4 wires. Possible bad Engine Coolant Temp Sensor. Temp gauge at mid-range as soon as the key is turned on; but that's not new, has been that way since I bought it. Never kept it from running before. Can't find Crankshaft Position Sensor to check. Is it on the backside down under the fuel rail? PCV rattles properly. Check Engine light has not come on since the day I bought the car. It was on and the mechanic said it was an oxygen sensor. He said he replaced it and the light has never come back on, not even while starting. I do not know if he did something to disable it. I hope it is not the PCM itself. What could cause this sudden problem?
Thank you for any help you can provide.
