DTM Brian Posted August 17, 2009 Report Share Posted August 17, 2009 For talking me today about the LT1 car. We installed a new coil and control module. We are still having severe misfires. I think the customer is going to order another Opti Spark. Hopefully this is the fix. Thanks again. Quote Link to comment Share on other sites More sharing options...

MrMeanGreen Posted August 17, 2009 Report Share Posted August 17, 2009 I wouldn't have thought so since the one on there is new. Optis aren't the most reliable invention ever made. Call me tomorrow if you need anything. Quote Link to comment Share on other sites More sharing options...
DTM Brian Posted August 17, 2009 Author Report Share Posted August 17, 2009 Thought I had your number saved. Wanted to call you. It is still on the dyno as we speak. Trying to get an opti spark for it in the next day or so. The longer it runs the worse it gets. Car would not fall out of tree. What is weird is we made 4 pulls on it with no problems and on the 5th pull the car had a bad hiccup and started missing at 4000 rpm's. Everyone on the phone today is saying the Opti spark.

mkent93 Posted August 17, 2009 Report Share Posted August 17, 2009 Is it a boosted car? NA mild cam car from what I was told. Brian, no problem, you can call me whenever. Was the fuel pressure ok? Quote Link to comment Share on other sites More sharing options...
Jackson1647545504 Posted August 17, 2009 Report Share Posted August 17, 2009 Just a Cam and Long Tubes. Gotcha ... I had the same problem but mine is boosted at about 15psi ... ended up switching to a crank trigger Still ... optispark sucks and almost anything is an upgrade ...

sprayin77 Posted August 17, 2009 Report Share Posted August 17, 2009 msd blaster coil? or stock? msd distributor or stock? Platinum plugs? whats the fuel pressure. Is there any chance the spark isnt hot enough for the fuel that is being deliverd? Quote Link to comment Share on other sites More sharing options...
DTM Brian Posted August 17, 2009 Author Report Share Posted August 17, 2009 Car made 4 clean pulls in one hour on the dyno. I even flashed the car with the tune that the car had for the last month to break the motor in and still the same problem. Quote Link to comment Share on other sites More sharing options...

schmuckingham Posted August 17, 2009 Report Share Posted August 17, 2009 Its because previous to those 4 pulls it had coolant leaking all over it from the water pump hose they forgot to tighten up Quote Link to comment Share on other sites More sharing options...
MrMeanGreen Posted August 17, 2009 Report Share Posted August 17, 2009 Its because previous to those 4 pulls it had coolant leaking all over it from the water pump hose they forgot to tighten up That wasn't mentioned to me. Had it been, I woulda pointed at the "new" Opti as well before the coil or ICM. Quote Link to comment Share on other sites More sharing options...
Richard Cranium Posted August 17, 2009 Report Share Posted August 17, 2009 Another question would be whether or not the "new opti" is an ebay POS, or a quality part? Quote Link to comment Share on other sites More sharing options...
DTM Brian Posted August 17, 2009 Author Report Share Posted August 17, 2009 Mr. Kent gave me a couple numbers to get an OEM piece for a good price. I was not aware of one of the hoses leaking on the opti. Quote Link to comment Share on other sites More sharing options...
schmuckingham Posted August 17, 2009 Report Share Posted August 17, 2009 Mr. Kent gave me a couple numbers to get an OEM piece for a good price. I was not aware of one of the hoses leaking on the opti. The opti is located behind the water pump, alot of the problems GM had with the opti was the weep hole in the water pump would leak onto it and make it fail. The car came to the shop leaking so it was a matter of time before the opti took a crap Quote Link to comment Share on other sites More sharing options...
MrMeanGreen Posted August 17, 2009 Report Share Posted August 17, 2009 Well, now I know. Yeah. Leaking ANYTHING getting the Opti wet = new Opti in the near future. Quote Link to comment Share on other sites More sharing options...
