Hi guys - have a 1993 camero LT1 - was runing fine - and stalled - let cool for about 5 minutes and it will run again - but than stall - have it at a garage and they say it is the opti that is bad - they came up with there option based on error codes 16 + 36 but also they where getting 4.7 Volts which the mitchel flow chart says opti

would a opti give this symtom where the unit will fail after afew minutes - or would that most likly be a control module

I have read about alot of similar problems and it seems more like a CM

thanks

Rick
