Yep I'm getting the 33 and 42 code. Engine runs about 25 sec's and dies but starts right back up. I can prolong the time by working the throttle.
My question: How to check this?
think I can check the green wire at MAP over 4.8 theres a short.
If under 4.6 all wires ok. I think the MAP is good tried three new ones samething.

Next if I check the vaccum from the TBI what should I get?
I've run the line from the TBI and instead of to the MAP; into my vac guage but no reading.??

How and where would I go about checking the manifold vacuum pressure? Could that be a problem? Have read that it needs like 18-20 lbs. of vacuum.

thanks
