Accel Gen 7 start up and high rpm problem

[Jim Nilsen]

I am currently having a problem with the car starting up and idling, I have to push the pedal when it is firing and it will rev up and then idle, otherwise it dies. I also have a miss /breaking up at 5500 and above.

I had a bad backfire and it has been a problem since. The IAC was whistling on start up much more than it ever had. Everything else seems to be good and it has a lot of power thru the whole range until it gets to 5500 or more. It varies a bit and somtimes goes higher and will go to 6400 at times.

The springs, pushrods and ignition have been checked and a new rotor and cap were also installed.

I think the IAC was maybe damaged from the backfire?

I sent Mark Remmel a private message to see what he thinks and am also looking for other thoughts as to what might be the problem.

The car was running great and would pull to 6400 and go the rev limiter at 6850 with no problems and ran really strong, now just before the Motorstate it is acting up.

Thanks for any help , Jim
