[QUOTE="toomanytoys, post: 16340027, member: 112770"] Ok quick update: I haven’t done the back pressure test yet because the car had to be inspected and running the car with no o2 would have set a code and that’s a no-no here in the great state of NY. But I do have new information if this helps. The misfire and stumble are load based. If I get on the car smoothly at a light no problem. If I give the throttle a quick stab it’s stumble city. I can get on the expressway and have the car rev up to 4K rpm no problem. Try to pass and stumble comes ( sometimes with a couple of lean pops through the intake). If the car is idling in gear and I try to powerbrake it it just coughs and sputters but in neutral I can rev it to 4K easily. I don’t know if any of this changes anyone’s ideas or opinions but I thought I would put it out there. Now that it has been inspected I’m going to try the back pressure test and see what happens [/QUOTE]
