With the price of gas, it would seem like an FSM would be a good investment. I am not sure about the check light....seems like there must be some way to check engine health....you might not have injectors but you still have an oxy sensor. Remove the air filter and inspect the choke plate while it's running. Try some acetone <img src="/forums/images/graemlins/wink.gif" alt="" /> ZUK

Believe me, I'll try damn near anything at this point. <img src="/forums/images/graemlins/drunk.gif" alt="" />

I do have an FSM, but unfortunately, mine being the last of the 4WD carbies, and being a Cali model... Probably one of the more obscure ones out there. I'm not even sure it has a pinout for the "ECU"

The one other thing I remembered, is I do have a very small leak between the cat and the cat-back at the flange; I need to get a new crush gasket. I really don't see how that could be affecting this that much, though.
