Subject: Re: opti question by Fluff on 2010/7/10 6:59:08 I'm just thinking on my feet really (bit like the 'dark garage/arching suggestion) and I'm no GM guru, but I wonder (others might verify):- When you say it sounds like a diesel, do you mean it literally?. Does the engine run better worst at idle or higher revs or under load (being driven)? Was there any chance that water got into the air intake/filter or perhaps the crank position sensor connectors? I've never taken my opti off, so hopefully someone will chme in, but I read sometime ago in another forum that the opti driveshaft can be 'force' fitted 180deg out... I don't know if thats true!?!... anyone? Do you still have the old opti?. I wonder if it didn't actually get badly damaged by the washing and now that you've found/fixed the arching it may have just been water in the HT... lots of work I guess just to try the old opti so I don't know if it's worth it!?. Do you have a good quality induction timing light?. I know you can't time this engine, but (on other cars) I have sometimes found bad HT by connecting a timing light to each HT wire in turn and just watching the consistency/strength of the light shining on the crank pulley. As said, just idle thoughts from a non GM techie... the guru's will probably say I'm off the wall and definately will have better suggestions. |
