My guess would be a potential bad CAT (agreeing with a coupld others that have chimmed in). Sounds like it's not flowing exhaust out like it should and sometimes it does. BUT, before dumping ANY money on it, you mentioned the check engine light flashed on. This means an internal diagnostic failed on the car and the computer has some data stored regarding what happened. From what I've seen, most cheap ODB-II scanner read current and history codes. I found messing with a Snap-On Scanner is can read current and history codes BUT can read other code storages on the car, such as last code thrown, last code thrown since last cleared, and codes thrown during this ignition cycle. Bottom line, the light flashed, there's a code stored in there. Retrieve it and share what was found, it may further confirm the problem as a CAT or point you in a different (and hopefully correct) direction. |

I had a restored 1976 El Camino Custom 350/2 automatic. The same symptoms you mentioned on your car happened on my Elk. Since it was a restoration, I had gone as far as to install a new CAT as well to keep it all all original. Long story short: Same problem as you. Turned out that for whatever reason, the new CAT was bad and did the same thing. I'm not sure exactly how you would test it for flow-rate but I sure concur with the other members. Hope you get it fixed soon!

No just taking it to a local spot. So if its a bad cat what route should I take without getting raped ? I heard someone talking about a high flow cat on zzp is much cheaper then stock.
