i did not check them this time, they were fine before. i just got my ecu back today, i had it redone , thought that would fix timing issue but it did not . i`ll check tps and map readings in the morning. i really dont know what else will cause this issue.

i` ve checked all my wiring and grounds, i forgot to mention that will on live data on scanner, the crank and cam rpms at idle are abouy 150 to 200 rpms differance. when i rev to around 1700 they are within 50 rpms of each other. i thought they should be 2 to 1 at all rpms
