AManiscalco2007 -> DTC Code 301 and rough idling.... (1/2/2008 6:16:21 PM)
|
I own a 1999 Hyundai Elantra 2.0 Automatic Transmission vehicle. I took it to Autozone and they printed out a sheet with some DTC's on it.
PO732
Gear Ratio Incorrect
PO442
Evap Emission Control Leak (Small)
PO301
Cylinder 1 Misfire Detected
Since before I first had my car serviced at Hyundai a few months ago. There were other codes stored in the ECM that were.
PO747
Pressure Control Solenoid Valve Stuck On
PO743
Torque Converter Clutch Circuit Electrical
PO732
Gear 2 Incorrect Ratio
PO734
Gear 4 Incorrect Ratio.
At the time I took it in, I changed the Transmission fluid and filter and then all of this happened to my car. I don't have reverse currently and it use to slam into second gear and the overdrive gear is out. If I try to put the overdrive switch on it will just rev up.
Now, I am having problems with the car idling very rough in idle and throughout the srive shifting.
I check all of the plugs and wires and attempted to check the Primary on the coil from the supply connector #3 with key in the run position (Not running) and there is no power but, the car does run????? Any ideas on all of this??? LOL, it's alot I know but, any help will be appreciated.
