l67 e85 stumbles and dies after wot pull.
Car was dyno tuned by a respectful tuner. I did a scan and i can try to point out the issue,s I notice that anytime i am off the throttle the iac go to 0 but if the car is on a wot pull when i let off the throttle it stays at 0. if i touch the throttle a couple times i can catch it before it stalls and kills the engine. last year if i ran a bigger pulley it would not do it only if i dropped pulley size. Lets say from a 3.5 to a 3.2. Also it also has a miss fire while accelerating i would catch the spike drop out on the log. correct me if i am wrong but does the crank senor send the signal to the icm? would that be why i see the dip in the log. I do have a wide band installed and was also tuned using one. gauge shows 14.6 cruising and 11.8 during PE. thank for any info. Attachment 89235Attachment 89236
