The MAP sensor tube needs to be perfect.

How are the plugs, wires, cap and rotor? ALL need to be replaced every 30,000 miles.

You're wasting a ton of money needlessly on parts as you probably realize.

Are your intake manifold bolts loosened up? Check them.

TPS is adjustable. Did you adjust it?

You need to go to www.cruiser54.com and do Tips 1,3,4, and 5 ASAP.

Keep reading Cruiser's page, he shows you how. I made one with his parts list, works like a charm.
