Hey all, I have a 1988 ranger 4x4.
I recently rebuilt this 2.9L, replaced heads with newer style. I had a miss in the ignition that I could not figure out. I was told it may be the TPS. So I changed it and it lit up the check engine light. To my surprise though it then ran with no miss. I waited a little bit and noticed that it would go in and out of the check engine light mode, revving high and miss a cyl. when it was not triggering the light. It would come back to idle and not miss when it lit the check engine light. So I unplugged the TPS and it did not miss fire any more, but now I have no throttle response and the light is still on obviously. So I was wondering if anyone else had come across similar symptoms with their 2.9L.
Is there a certain way you have to install these?
Thanks for the help
