I failed emissions today
I failed on 2 areas. Low speed Hydrocarbons too high, easy one to fix. Run the test in 1st gear and get the revs up, hotter exhaust gas will help to burn off the excess carbons and the RRFPR dumps fuel in on the low end, higher revs would help with this.
The second area is the real shocker. I failed because the CEL is on with 7 codes. CEL bulb was removed because it sucks, my guy looked the other way on that and a few other aspects of the visual test.
Here are the codes.
P0743 TCC circuit electrical failure
P1761 Shift Solenoid Malfunction
P0753 Shift Sol A electrical
P0758 Shift Sol B electrical
P1423 Secondary Air Injection failure
P0443 Evap Purge Valve Open or Short Circuit Fault
P1174 Fuel Trim Adaptation Additive Bank 1 Malfunction
Most of the codes cleared when hooked up to a scanner. The transmissions codes could be fixed if I swap my ECU with one from a stock 5-speed. Unless the VIN is programmed into the ECU? Are they? The one I don't know how to fix is the P1174 Fuel Trim Adaptation Additive Bank 1 Malfunction. Any ideas? Will swapping the ECU work?
Or should I get NickG stage 2 software to adjust fuel delivery on the low end and have it written for a manual if possible.
(this is a nice thought but not visible at the moment)
