OK I returned the 98 cobra back to a street car. So for giggles I reset the the fuel pressure at 40 with the line off and capped.
Then I messed with the TPS Voltage and experienced surging at idle. Then I noticed the car would die when coming to a stop.
I thought it might have been the old super chip I put in but after a few days of driving there was still an issue with the surging and stalling.
I have also been trying to find that nice spot for clutch engagement.
I was under the assumption I should adjust the TPS Voltage with the car running. WRONG!
It needs to be adjusted to 0.98 volts with key on engine off. I did this and my idle dropped to about 700 rpm.
The car is real quiet at idle. So now the surging is gone and the stalling is gone like nothing ever happened.
Another huge thing I noticed is my take off in first gear was amazing and all of the sudden found my sweet spot. Amazing that 200-300 rpms made a difference with how my clutch reacted on take off. I always felt as if I was feathering it to properly take off. This feeling is gone.
Just thought I would throw this out there if anybody else is have any similar issues. I'm curious to see if my gas milage with improve with the lower idle too. This is what prompted the super chip change out in the first place.
