This one looks like it would be emissions related. What kind of injectors are those?! Is the car tuned for them?? I'd be willing to bet your problem lies in those injectors.

That looks like A/C to me.

i had just placed those injectors in the car, theyre 36lb boys. they had after market ones in there already but the fire rings were drying out and all so i replaced them. the car was doing this long before i swapped the injectors out so i dont think the injectors are necessarily doing it. what could that sensor be though? and my cars pulling the 66 code its an ac code do you think the engines compensating for the loss of ac pressure?

You cant change the size of your injectors without a tune. Im betting thats your problem. Maybe it was never tuned for the old ones neither. Get a cable and tunerpro since you have a '94 and you will be able to tune that yourself.

Or go back to stock injectors. They are either 23 or 24 lb, if you didn't tune it for bigger injectors it will cause your problem. No, it is not compensating for the ac.

You really don't think bigger injectors and no tune for them would cause worse gas mileage Bigger injectors= more fuel dumped= shitty gas mileage....this is not rocket science. Either get your car tuned for them or go back to stock. (A bolt on car does NOT need bigger injectors...stock ones are good for 400 flywheel hp) You just said yourself it had aftermarket injectors in it already; then you swapped to these 36#...which is exactly why it's been a gas hog the whole time.

The computer could be trying to overcompensate for the excess fuel in the engine?? I really don't know honestly, but a tune should fix it right up.
