So I get this new engine and put it in, runs great! Thanks Garold, you're a lifesaver.
I dirve it for a while, and notice that cold idle is REAL low. Warm it idles just a tad low, but at idle it runs RICH.... lowered performance until 1500(small amount of bog), then peaks at power at 3500 I drive at around 3500 usually (keeps it cool) Idle it runs rich, so I adjust the knob on the ECU, and I dont want it to run lean at idle. So back to the notch it goes, where its rich. I have 3 Mps's in all, including the Type III one which doesnt have a diapragm as noted in another buried thread....So in all, I have four MPS's. The one currently in the car is the "NOS" one that I paid too much for from a member here. Whatever. It didnt leak down a year ago, so I assume its still good, being that I just now used it. In four days im getting into rust repair, upon which the engine will be dropped...mayeb then I could do a valve adjustment and take care of some things. It's has some clicks at idle, maybe from the valves? For the rich thing, maybe the trigger points went bad? I'll try some from the VW guy tomorrow, he has a box with a new one in it, or i could pull one from a rebuilt dizzy I have from cardone. Any comments (less the "sell the 914" ones) add them below Car runs though! b |

Idle during warm-up is controlled by the TS2. When operating temps are up to normal, or when the accelerator is moved, the switch inside the TPS or the warm engine condition signals the ECU to control pulse width.
Verify the resistance values hot and cold of the TS2 with the Anders page values. Your TS2 may simply be going out. |
