Check around the engine for a t connection behind a canister on the passenger side. The tube connects to a port just to the right of the throttle body. You will need to remove the intake air cover to get to it ( this is all according to what ive found on google, also its on a 97 but should be similar)
The mode door is located in the “dog house” which houses the evaporator and all that jazz
Usually you check for leakage or sagging springs. Also you can try bouncing the rear bumper a few times and seeing if it bounces excessively. If not, personally I wouldnt worry about changing them
according to mitchell on demand the FPR is on the fuel rail. Go to google and search for a picture showing the location, it wont let me post a link on here!
Im thinking along the lines of a vacuum leak as well, the fact that it revs to 3k on its own leads me to believe that. Ive had a few cars do that very thing and it was a simple vacuum leak
I think the mode door on that model is vacuum operated so perhaps you have a vacuum leak or something along those lines
Yeah pretty much, sounds like you have a dead fuel pump. I just had one go out on my truck last month…. boy that was expensive
The fuel pressure regulator should be mounted on the fuel rail, it will have a little vacuum hose on it. Start the engine and disconnect the vacuum line connected to the FPR. Hold your finger over the hose and watch the fuel pressure regulator for several minutes to see if fuel sprays out of it
I would loosen the jam nut first, do what ever you gotta do to loosen it. Then after that remove the cotter pin and nut from the tie rod end and separate it from the knuckle
I’ve heard of fuel pressure regulators causing similar problems (at least on GM vehicles) the diaphragm in the FPR can get a slight tear and cause fuel to get sucked into the vacuum line after the engine is shut off. Basically it momentarily floods the engine but then goes away
