Hey there.
I have a 98 GTP with 172,000 k on it. For a while now I've been having to hold down the gas a little bit to get the car to start. Even then sometimes it will idle down below 500 rpm's then stall. The car will not start at all unless the gas is depressed.......

I've been reading a ton of articles on this forum and just can't figure it out.
I've recently replaced the plugs / wires / fuel filter and several other maintance items.

Please help...
Thanks...
