ECM malfunction codes

[Wookie]

Please help! I'm receiving multiple malfunction codes on my turbolink v2.14. My ECM seems to throw out random malfunction codes when the engines under load. I have replaced the ECM. Also, I have a new TT chip. Malfunction codes occur with both the new and old chip and was happening before I replaced the old chip.

You've probably got a loose wiring connection somewhere or possibly a bad ground. Be methodical about it when checking. I'd start with cleaning the battery terminal ends and then the ground conections (on the passenger fenderwell and back of the passenger cylinder head). HTH.
