Yes the Trooper is MT. It runs. In fact it doesn't even miss. Trottle response is very slow . You can floor board it going up a hill in second, it won't cut out. I shift down to first just to get up an average hill. On take off in first, unless you give it lots of gas it well stall and die. You can tell it is in some kind of shutdown. When I start it it does not rive like it used to when cold., just sits in idle and slowly starts to die. then will catch and go back up to idle speed between 8 and 11rpms. I have checked all the emission lines by the book and pics I have seem on here. I am going to recheck again today. I thought if it is one of the emission components it would at least sound ok when it starts, then act up a little later.

It was a sudden change I pulled off the street to take a phone call. I turned off the engine. When it restarted it was imediately sick. the ecm popped a few times engine light came on two or three different times, Now engine light does not come on any more. except when I start it.

My Chilton book says if the ecm is bad the truck will go in to a default mode or limp in. The truck can barely get to 4th on a flat road. Possible both ecms I tried are bad I suppose. The pins sure did match though. I can't find an exact match year for year, model for model yet. I will keep looking though. If you need more info let me know. I'm not sure where to start looking at this point. Thanks alot, Stan
