Okay, My '76 280 ran fine till the other day. It sits in the garage more that it gets run. I got on it and ran through the gear hard as it would go till I got to my driveway. Pulled in and shut it off. When time came to leave again it idles fine but wont take the gas. I disconnected the cold start injector to see if it was stuck on (didn't help). Over about a 1/4 throttle it boggs and backfires through the intake occasionally. I am sure one of you other Z drivers has had something like this happen before. Give me a clue if you can. Thanks.

 

I checked it and the air flow sensor and it was stuck.

Man...glad that problem is delt with. Thanks for the input tho. BTW sweet Z you have there.
