Hi All, new to the forum, but not to working on cars.
I have a 2004 Anniversary Edition 3.8L 5spd, and I'm having some trouble with it. I wanted to test fuel pressure, because the car is bogging down when taking off from a stop. You literally have to just push the gas and pray it doesn't stall out before it begins to accelerate. I rented a tester thinking I could at least rule out the pump and filter instead of just throwing parts at it, but instead of having a fuel pressure test valve, there is only a Fuel rail pressure switch. I thought maybe underneath it would be a valve to connect the fuel pressure gauge, but it's just a smooth hole with no valve or threads.
I'm wondering if there is a separate adapter I need to find or a different place to measure the pressure manually. Or maybe someone has had a similar issue with their car, and knows something better to start with.
I have recently replaced the plugs and wires, air filter, belts and hoses for maintenance, but this problem is getting worse. I also had to replace the linkage rod bushings for the IMRC. Maybe it's stuck closed, but how do I tell? I don't have a scan tool. I bought a USB cable to connect to the OBDII connector, but haven't found any affordable SW to use it with. The seller screwed me over and never sent the code for the SW.
Anyway, enough rambling. Thanks in advance!
