My 89 will start, but it's running rich enough to set off the carbon monoxide detector in my garage with the doors open. And it dies, won't idle. I have to keep feathering the accelerator pedal.
I know it's due for a top end refresh, but it ran great before we installed the supercharger.

Just replaced the Hall & CPS sensors, new fuel pumps, filter, etc.

I'm not at all good on electrical problems, I have less than zero knowledge about what I'm doing.

Suggestions please!

 

Temp 2 sensor resistance output values OK?

 

I'll check it out. Thanks Fred!

 

Age of the Fuel pressure regulators?
Age of the MAF?

 

Victor's S/C setup, correct? Injectors changed to 24#? And the ECU chips both changed to PEMs? The symptoms sound stupid rich, which could be 24# injectors and stock chips.
When are you off to the oil patch? Do you have time to talk in the AM?

 

Sure, do you have my number? Victor, changed the chips and we sharktuned the car. I have the stock chips in my gun safe.

 

And it idled OK after Sharktuning?? What changed since then? Fuel pump shouldn't be an issue, FPR sets the pressure.

Please PM phone#, I just sent mine.

 

i suggest testing the fuel regulator snd dampers to make sure they hold vacuum and are not leaking. my 89 regulator pours fuel out of the vacuum port. ordering a new one tomorrow.
