Just recently my car started acting up. Almost whenever the clutch is pushed in or the car is in neutral and at normal operating temperature the car will not find idle. The idle on the car is set around 850rpms and now it bounces around from 200rpms, borderline stalling out, to normal idle. Becasue it is tuned the check engine light does not come on for minor things im assuming so I hooked up the diagnostic reader and this is what i got back

1: P0102 MAF or VAF circuit low input
2: P0133 O2 sensor ckt slow response (bank 1 sensor1)
3: P0135 O2 sensor heater circuit malfunction (bank 1 sensor 1)
4: TPS sensor circuit low

If anyone knows anything about these codes and could provide some helpful input I would be very appreciative.

If it's also harder to get the shifter over to reverse I'd check the ENG SEN fuse.

I bet that's it.

Yep thats what it was, thanks guys. It is crazy to think that one little fuse can screw up all of that stuff.

Question is why did it blow? If it happens again you'll have to look at everything on that circuit.

The purple seal/gasket thingy where the connector goes into the tps was bunched up and some grease or something was on the connector and im hoping that is what it was. If it happens again I will have to do some investigating into the problem

Another common problem is the o2 sensor wires getting melted by the exhaust system.

Where is the engine sensor fuse? I was throwing 5 codes, but I found out it was my passenger O2 extension that was melted on my header. I replaced it and now I'm throwing 3 codes.
P0102- Mass or Volume Air Flow Circuit Low Input.
P0801- Reverse Inhibit Control Circuit Malfuntion.
P0803- 1-4 Upshift (Skip Shift) Solenoid Control Ciruit Malfunction.

I cleaned my MAF and I even switched with my friends MAF and its still throwing the code. The connectors seem fine and not corroded.

Did you find it? It's under the hood in fuse relay center #2.
