I checked the fule pressure and gas shoots up out the valve. Wrong! that's the wrong way on checking fuel pressure-you need a fuel pressure gauge to check. The EFI is very picky on fuel pressure. Not right it might refuse to start

Comeback with the actual fuel pressure in the system before we can continue-I need to know this. So that I can re-evaluate your problem is to whether its a fuel or ignition problem.

Subject: stumbling on acceleration
When I changed Maf sensor the engine stoped idleing in park or in any position when not accelerating. but when I rev the engine or try to take off it starts stubling on acceleration. there is no check engine light and I just changed the control module and coil so what should I do next?

Next step check the IACV and TPS and also check the EGR
