Ok sorry about the long time no post...but been having alot of issues with my bonne...it is basically falling apart at 160K now. I ordered a new cat for it and midas will put it on for 75-100 depending on what needs to be welded, because now at low idle on the highway my car'* engine is shutting off, I assume because the cat or exhaust is getting to hot or clogging. So I put it in park and restart and it comes right back on. But I know it is because of the exhaust and/or cat issue. I bought some seafoam to put in, but need some advise where is the best place to put it in the gas tank or the oil tank? It states on the bottle it can do different things depending on where you put it...I think to get the most benefit from it I would need to put in the oil crank. Please advise on where it should go.
