[s-cars] 034 Motorsports coil conversion harness

[Odyrestorations at aol.com]

Tom - 
 
Thanks - good thoughts. I think I will try Dave's suggestion 1st because I  
never experienced fuel shutoff due to overboost before, so why would it  
overboost now?  My problem before was an occasional miss at full boost that  slowly 
degraded (over a period of 6 - 10 months) into more and more missing  at full 
boost - not cutoff, but one cylinder, maybe two dropping out. This seems  a 
classic ignition system problem on these cars. 
 
I drove the car to work today and noted the total cutoff at full  boost.  
Driving home, it began to cut out at more moderate throttle  positions - pull 
over, pop the hood and find 2 coils popping up, so I really  need to heed Dave's 
advice. Although it is still odd that I do not get a misfire  in one, or two, 
but a total cut out of the ignition. 
 
I'll get those suckers to fit tightly and report back....
 
Thanks.

Tom,

Are you sure that you have total ignition cutout and not  total fuel  
cutoff?

If you do know it is ignition cutout, then  the path suggested by Dave  
F could yield results.
It probably  needs to be done anyway.  034 stands behind their  
products as  well as any
one, so I would think your investment (less labor :-) ) is  safe.

If you are not sure, I would be suspecting fuel cutoff because of  an  
overboost signal to the
ECU, probably from a boost leak at one  of the hoses.  This would most  
likely accompany
one or  several malfunction codes and probably a MIL light.  Checking,   
recording , and
clearing codes could be useful in  diagnosis.

Tom
