HelloCustomer As the owner of a LT1 engine myself, I can tell you that you are most likely right on the money. The opti-spark can give you that issue. If you replaced everything else, that even makes it more of a possiblity. They do fail and very seldom leave any codes in memory. The computer is probably OK and I would replace that opti-spark before replacing the computer. My car has 202,000 miles, I'm on my second optispark and the original computer. If my car sits for a week or so, I get a misfire that clears up. I know my issue is the optispark, but I don't feel like installing a third yet. I think your opti-spark will fix your issue.
Your JA Expert,
Yea that`s what I thout.
You're very welcome. It is the joy of the LT1. Let me know If you need anything else.
Hi Ivan, I`m thinking of a hypertech programer for the roadie(lt1 roadmaster) and wanted know if the clames of perfomance and ecconome are true. Also do you think buying one used is good idea, and what to look for in a good one.
It's a good idea. I've got one on my 94 Caprice LT1. It's a great source to alter you fuel curves as well as shift points. Even turn on the cooling fan sooner. Do it,you'll be happy. The Hypertech will serve you well. By that one.
Sorry it took me so long to get back to you my computer craped out on me. I`m looking at a used hypertech, is thair any troble to look out for in used unit.
