Ok, went crusing tonight, can ran Great!!! On my way home, crusing down the highway 1600rpm, the car kinda bucked for a slit second, then again, like an injector was clogged or the opti was misfiring??? I am trying to determine what the hell ca be causing this. This is soooo intermittent, happens once every so often. I replaced the pcv valve and that seemed to cure my ses light issue. The light has not come on since. Now, the plugs looked good, I have taylor wires that I ran over the valve covers, so there is no possibilty of the wires being burnt. Crusing tonight, shifting through the gears...it is all smooth. The shifter feels smooth most of the time, however, sometimes its more jerky that others. I really am coming to the conclusion that it's my opti that is giving me the headache. Anyone have a recommendation or what I can try? If I decide to replace the opti, can I go with that delta spark instead? I really dont feel like taking my car apart to replace the opti and the deta spark seems more reliable and a better solution. Some input would be appreciated.

 

I have the same problem with a new opti

 

you have an issue where you lose power for an instant and no code? Could it be the Mass Airflow Sensore? I am runnning out of ideas. Funny thing is, this will happen tonight, and for the next few weeks, it will be fine,,,
