Please see below for my modifications. I have been having a hell of a time with the car stalling when it is idling, especially when coming to a light at rpm and letting off the throttle quickly. The fuel pressure reg is reading 45psi when idling and when I blip the throttle it stays constant but jumps to 50psi when I let off and the car stumbles and stalls. Any suggestions? Things to check? I noticed that my wideband jumps all over the place too when I blip the throttle. Any suggestions/opinions greatly appreciated. The car doesn't get driven much (maybe 100miles a year around town).

Thanks,

Justin

Start by making sure your biss is properly adjusted. The tune need to be gone through, starting with insuring your injectors are properly scaled and trims dialed in. Then go through all the idle tables. You can also try increasing the idle timing slightly.

I didn't tune the car to begin with, I had a vendor on the forum do it on their dyno but it's been awhile since it was tuned(8yrs). I am not really familiar with tuning or using the aem software do you have a recommendation? I recently purchased fic 2150ccs bc I want to get a retune and run e85. So do you think it's potentially a tune issue? Injectors?

Thank you,

Justin
