I’d check the throttle cable, if you don’t have a good block to chassis ground it’s known the throttle cable will fulfill that need and cause sticky operation eventually welding itself to the sheath.

I’ve got the last lightweight Competition Clutch flywheel NIB sitting in my garage but I won’t be home for another 10 days, pm me then.

Likely yes, the relay contacts get corroded so they start to fail, take it apart to clean the contacts or find a replacement.

Link?

These engines are set up from the factory to idle closer to 12.5-13 AFR, even lower cold. There is a ground switch on the tip of the ISC plunger that, when closed against the throttle stop sends the ground signal to the ECU to go into idle mode. Idle mode bypasses the O2 sensor signal and keeps the mixture rich for best idle, maybe the signal is not getting to the ECU. That happened to my Starion way back when, I had to clean the connector contacts between the ISC and ECU after which it worked as designed. The requirement for rich mixture for best idle quality is why they came with the idle air bypass to feed air into the exhaust ahead of the cats for emissions control.

Hot start issues are often caused by heat soak on the IAT sensor, the ECU won’t add enough fuel until some air movement brings the sensor down.

There is a switch on the tip of the ISC that sends a ground signal to the ECU letting the ECU know to go into idle, is that what you’re seeing?

Yes, the factory setup used a power resistor on the negative side of the coil, little gold box thing. Remove that and wire tacho out to the white factory tach input and it likely will give you a working tach. I wrote up a mod in the MPI section but it appears lost.

I’ve had mixed results running the tacho out directly to the tach input, seems to work on the needle gauges but not on the digital dashes. Else you can make one of several adapters listed in the MS1 forums on msextra. I used to sell one made from a relay driven by the tacho out.

Got two in ND and three in Phoenix, might be able to deliver on our journey between, October and April.

MS has table editors/builders for each table you require, click on “tools” when in any table. Answer a few variables ( guesses are fine) and you’ll get awfully close. Close enough to start the engine and begin tuning. Best of luck!

Lost in translation. I am the Godfather of MS for Starquests, probably some stuff in the vendor forum left on my contribution to this community, maybe not. Motocam Tim carries my products still, don’t check in here much anymore.

It works just fine, 36/4=9.
