About 2 weeks ago my 94 formula startled me with an unexpected stall for a few seconds while driving. It then went back to normal as if nothing ever happened. Next day comes around and it happens again. (both times at low rpm cruise) Had mechanic look into it and came back with a problem in the distributor ignition system -DT 36. "Faulty High Resolution Pulse or Extra Low Resolution Pulse Detected" This problem has been occurring less frequently since then but it still occurs.

The diagnostic aid claims that the engine does not need the high resolution pulse to operate but I would still like to make a complete replacement on the cap/rotor/opti as the hose from my water pump had recently burst as well.

Relying on her, I would like to make a replacement with a dependable distributor/opti (not planning on doing the EFIConnections). What brand (MSD, Delco, OEM, Accel, etc....) would you guys recommend for dependability but no need for any higher rpms since I am not racing her. I am not trying to skimp out but I just dont want to invest the money for a badass set on a stock lt1.

 

Delphi, Delco will do..I would also replace optispark wiring harness connector if you still have the stock one..Don't for get to put locktite on the rotor screws.

 

+1 I found a Delphi opti on Amazon for $248.

 

Right now Advance Auto has $30 off online that BWD brand looks pretty good..It will be cheap if you use the 30's off you'll get it for 100 bucks..not bad.

 

Hmm I might just go to with delco. thanks a lot guys. have you heard anything about the Accel one on jegs?

 

Not sure if i wanna take the risk on anything under 200... the BWD seems to be just the cap and rotor btw

 

Chandler Motor Sports on ebay for 90.00. Brand new just bolt on. No need to pay hundreds for something that won't be any better.

 

I just bought a Delphi vented opti from amazon for 240.00. I had a ebay special, lasted about 2500 miles. Hard miles, but none the less the rotor screws backed out and killed it.

 

LOL, their [Chandler] track record says aren't the better one by a long shot. Read all the complaint threads. Honestly, how can a $90 opti be any good?

 

I am running 9's with an AC Delco opti. I loctited the rotor and sealed the cap and my car see's 7000 pms on a regular basis on nitrous. Two years and still going strong.

 

guess im going delco then
