89 formula, 5.7 TPI, auto.,no cats,k&n otherwise stock

here is my problem only when crusing at sustaind speeds(any speed) and i hit a bump my engine wants to die on me SES will come on and stay on for a few seconds then go off and the engine will pick up again with the smell of gas for a min or so.

when checking the codes i get a code 33 could the be a loose connection somewhere causing me to lose spark?

doesnt happen all the time(not every bump) and no particular speed or RPMs

tried new cap,roter,wires and plugs already

any ideas??

 

dieing MAF unit or loose connector

 

Try pulling off the MAF connector and look at the female pins in it. Using a small awl try bending the female "closed" a bit more so they make positive contact with the MAF sensor.

 

i will try that this evening and thanks for the reply!
