my 1994 z28 had some bad fuel issues that I think got aired out so when checking it out I had it reved to about 2500 rpm and my son was looking under the hood and noticed when I goosed it a little the air hose that goes into the tb closed like you put your fist around it cutting down on the air intake. I have had it about 3 weeks and runs good the air filter is new,( I checked it when I bought it) it has the stock air clearner on it. it does have a high lift cam in it. would it cause it to need that mush more air? is it time for a cold air type set up? thanks in advance for your help

 

If the inlet was severely clogged, it might do that. Pretty unusual.

 

Are you using the stock ribbed 90-deg elbow from the MAF sensor to the throttle body? Did you check for something blocking the screen on the inlet side of the MAF sensor.

 

it is the stock setup that comes on the car I think... I will check the screen in a little while. sorry it takes me a while to answer long hours at work thanks alot

 

sorry it took a while to get back to yall. I had lightning hit my house and ruined my electronic gadgets in the house so it took a while to get everything fixed....I went ahead and took everything apart and found nothing to stop the airflow so I went ahead and swaped the air box and filter to a fresh air type. seems ok now thanks again
