As I was inspecting and putting things back on my car yesterday, I noticed something wierd on the T1 coil covered w/some piece of brocken plastic which made it suspicious, when I took a closer look, the coil actualy was cracked open and the piece of plastic looking crap was actualy a the crap that came out of the coil.

A while ago I noticed a funny hasitation around 4-4.5 K RPM on slow acceleration, but if I floored it there would be no hasitation at all, I guess this coil explains it.



Check out the pic...




P.S. Thanks to Fritz Flynn, I just got one from him...

 

One should never say never, but...

Usually a bad coil will act up at higher RPM's and under increased load (higher boost), so that may not have been the cause of your hesitation.

 

That's exacly when my car hesitated, @ higher rpm, 4-5 K is pretty high, but not neccesarely while boosting though. It actualy happened more noticable if I held the RPM 4-4.5 K without boosting, and as long as I stayed at that rpm the car would constantly be hesitating/shaking.

 

thats happened to me with both coils, it caused low-mid range rpm hesitation. the cause of it was the wiring harness. i had extented my wires to mount the coils on the fender and wires melted and touched. make sure you check all wiring and protect them from heat.

 

Speaking of wiring harness, I isolated it completely, also because all the unnsecesary solenoid removal.


Here's a quick pic I took w/my cam. phone, I'll get alot better ones later.

 

at full bore the trailing contribution is prob pretty small so you dont notice it missing

 

Yep, that's exactly what happened...
