Car is a 73 2.0, new TPS, new FI Points, new TS1, existing TS2 (its the 017), all intake runners, hoses, gaskets, and PCV are new, injectors were cleaned and serviced by witchhunter. Also all parts are correct for the 73 2.0. I put a 270ohm resistor in too. Car seems to run lean at idle (I have an air fuel meter).
I had the wrong TS2, because I replaced it with what I thought was the correct replacement. Upon further review, I put the used 017 piece back in. The car had been sitting when I bought it, so I dropped the motor to take care of a few problems, and I refurbed the FI while I was at it. Car seems to have good power and pull hard, but it doesn't seem to idle quite right. It oscillates between, 1000 and less than 500, while the air meter reads lean. Air bleed and the knob both effect idle, but I can't get it to stabilize or richen up on the meter. Also, I have a euro-race header and MSD. Should I play with the resistor or the FPR to richen the car for these parts? |

Run the engine to operating temp...At this point, you still have the idle hunt, Correct ?
Just for fun...While the engine is running, hunting for the correct idle, unplug the temp sensor on the top of the intake plenum...Does it stop hunting ??? It did on mine, never could figure out the reason, it just stopped hunting and stabilized the RPM...Perfect idle after that...Did the exact same on my current 1.7, so I just left them unplugged... The down side is that it will make the system run rich, but I compensated for that by turning down (counterclockwise to Lean) the adjustment on the ECU...I know that is not the correct answer, but it works and the car(s) run great... If you take this approach, be sure to cover the harness plug so water does not get into the plug... Sorry in advance for the bad advice, but this works... 2-OH! |
