Rough Idle, Codes Problem, Need Help
Ok, to start off, I'm completely new to Powerstrokes, so any help would be appreciated.
I have a 96 with 160k on the odometer. The truck had an edge 60hp EZ chip under the hood, and an Edge programmer on a 100hp tune in the cab when I bought it. I don't think that the stock injectors could keep up with both, so I took out the programmer. Cold starts, ( it's 5-20 degrees here in the south dakota in the winter) it starts and has a slight miss for about 10 seconds and then it evens out, but it would smoke for 10-15 minutes after starting it. I unplugged the 'ez' chip and it got a little better for a day or two, and started again.
I ran a contribution test and #3 po269 and #4 po272 were showing up. So, I swapped the #3 injector with #5 and ran the pickup for a few days. Later I ran another contribution test and 3 and 4 showed up again......So, I assume the injector is ok. The harness under the valve cover seemed ok, everything was connected.
I ran a buzz test and it gave me #3 p1273 Code, and wouldn't test any other. It seem kinda low on power too...Anything I should look for? How should I test the harness under the valve cover?
On another note, I get a po236 Turbo A circut code. The EBV is sticking.
I appreciate any input guys, thanks alot.
