Now that one car is running well it is time to get my 90 Sc running again. About a year ago I put a new engine in it I bought from Matt Haub(Dr. Fishbone). Once installed it ran great for about a tank of gas. Then I had an issue( don't remember what at this point I time). Fixed that and ran about a tank of gas through it and yet another issue. Always seemed to get about a tank of gas through it before another problem arose. Finally I barely made it home one night. I needed to keep it in boost just to get the car home. By the time I pulled in the driveway it was idling very roughly about 400 rpm. I pulled it in the garage the next morning and from that point on it would not restart. I borrowed a DIS module from Mike Inch(Bumpskier45) and got the same no start condition. Today I decided to put the trickle charger on it to have the car ready for when I had some time in the next few weeks. Battery appeared to be pretty well charged so I decided to pull the chip and see if it would start. Much to my surprise it did but was running very very poorly. It needed throttle to stay running but would not rev over 1000-1200 rpm. Letting go of the throttle the rpm went down slowly until the car would die.
Being that the car all of a sudden started and ran without the Quarterhorse in place is that an idication that the battery on the Quarterhorse is dead? I have another chip I bought at the same time on my Mustang and it has seen a lot more use but has given me no trouble.
I have recently had some issues with my Mustang that mimicked those of the SC. It turned out to be timing retarded too much from some widely gapped plugs. I am wondering if the knock sensor isn't the cause of my issues right now. The engine had sat for many years before I purchased and installed. Would this be a logical place to start looking?
