Re: Hesitation/lack of power
Try the fuel pressure at 6 psi for starters. Trans oil level is OK? If you use a 2 step change the 2 step module. Had one go bad when we had our Malibu stocker causing same grief.

Re: Hesitation/lack of power
No on the fuel sloshing as it will act similar in park stabbing the gas. Checked the fluid and it is ok. I tried leaving without the two step and had the same results. I will try the fuel pressure on the next run. Thanks for the ideas

Re: Hesitation/lack of power
Squiters doing as they should? Good flow out of both sides? Rear air flap OK?

Re: Hesitation/lack of power
Check the accelerator pump gasket, they dry out from sitting especially after using VP fuels. Chased that for a while once.

Re: Hesitation/lack of power
Described hesitation is usually too much or too little fuel. Too much and you'd get a black puff when it finally picked up. Too little and it's just a dead spot. I'd bet too little. I'd start by dissembling carb and cleaning thoroughly.
What carb does it have? |
