Default Opti looking for a second opinoin

Car does not want to stay running.

I have power to the coil. And on a spark tester its not jumping the gap so . I grab a coil and it did not solve it.

Bust out the Multimeter and I have 1.2-1.7 ac volts on the opti signal wire while cranking

It just sits there and back fires like crazy and I have to pedal it when slowing down or it will just die. I have to Heel toe while stopping

At idle it only sits at like 10psi map at 900 rpm and I can not find a leak with propane or starting fluid. It all started when I was driving in the rain a few weeks back and it back fired and died but then It was down for two weeks while I changed the clutch, Now the past two days its gotten bad and worse


So is it time for a new opti or what? Let me know if you want more information cars torn apart in the garage Thanks guys

Most "dead opris" are just worn out caps and rotors, but most folks here are too stupid to understand those should be normal tuneup items and curse a good piece because of their own neglect.

I agree with above, cap and rotor most of the time will fix it w/o spending the money on a brand new opti

No a cap and rotor will not fix a resolutuion signal, but how many of those are caused by leaving the cap and rotor go till spark starts going the wrong way?? Like oh say back through the electronics.
