![]() You could buy or borrow/rent a fuel pressure gauge and hook it up to the schrader valve on the fuel rail and read fuel pressure. I believe for your vehicle (if i were to guess) you should have 35-40 psi of fuel pressure with the key on.
Also pull the plugs and see what they look like, if they're glazed and white then your vehicle is running lean, if they're covered in gas....it's rich. Also on heavy acceleration is there any black smoke coming from the tail pipe. The catalytic converter may hide it running rich because alot will burn in the catalyst. You could also look underneath your car and see what your catalytic converter looks like. If it's glowing red it's running way too rich. Hope this helps
