Opti spark

[Cruise]

I was told that since I have to replace the opti spark on my '94, I am better off buying a vented '95 or up version.

Any thoughts on if this is recommended?

i used a 92 base with a 96 vented cap. works fine. i ran a hose from the vent around inside the finder and put a fuel filter on it. one of those clear plastic jobs from auto zone. i figure it will let it breath and trap any water. been about a year now with no problems. robert

There is also something under the "Knowledgebase" tab above under the engine section I believe:

Question

Has anyone ever just ditched the optispark, and put on a different type of ignition system??? Is this a crazy idea??

I did the same as robert with my opti, works fine after a little over a year at least the last time I ran it. Too much salt on the roads to run now. Don't know about conversion.

How to detect a faulty Opti Spark

How exactly can I tell if my opti spark is actually defective?

Eractic idling is the most noticable issue from the engine.

My drop down gear is not working anymore ( 4 speed automatic )and neither is the ASR.

I have had my local mechanic take the readings off of the computer and they have replaced the ECM and TPS, however the car is still running poorly.

Any thoughts?
