Hello i am new here and was wondering if i could get some help.
I have a 350 TPI marine intake style. That has been modified to a 430 It was built by Hesco in Alabama. IT is a Dart Block and heads. Ran great before i put it in storage for about 3 year. Whats happing is when you start to accel it starts to drop left bank and right side starts to load up.. This happens around 2000 then clears up most of the time around 3200. I have check everthing. Replaced 02 sensor CTS, ATS, ECU and it still does it. But if i disconect the Air temp sensor on the air box it runs great. I replaced the ATS sensor thinking this was it and problem is still there. At idle my TPs sensor is at 0.56 CTS is reading 96c And ATS is reading 30c. I am ready to burn it. Can some when help.... Thanks a bunch. Jason
