Hi. Im brand new tothe forum. I have a 96 cobra superchipped for 35 hp and removed rev and speed limiter, k&n cold air intake with stock maf, bbk high flow cats h-pipe with side exhaust, hurst short throw shifter, 3.73 with t-lock, was planning on supercharging it very soon but plans just changed so i took out the stage 3 clitch i had installed last fall. I dropped down to a stage 1 this weekend and it went flawlessly until i finished up and started the car to get it off the ramps. The car turned over fine and then started and made a puff of exhaust then died. I chwcked everything out and it all seemed good. All hoses and sensors were hooked up but the right exhaust pipe wasnt seated on the manifold correctly i started it again and it was fine. Clutch is perfect short tight travel and engages very well. I drove easily around town truing to break it in and when i came to a stop light and had the clutch disengaged the car stalled. I strted it back up an drove it a mile home. When i got home the car was aluggish and was idling up and down between 800 an 1100 rpm harmonically. Does anyone have any idea what is goin on?!?! I cant track it down. Te exhaust still has a small leak on the passenger manifold im going o take care of tonight. I drove it 3/4 of a mile to work and it didnt stall or idle funny.
