SOURCE: Car hesitates/stalls when engine is warm and car starts to move.

Sounds like a bad motor mount, pop the hood and see if the motor shakes or moves rapidly when u put it in gear holding down the brake.

SOURCE: car wont stay running unless foot is on the gas

Withoutknowing if the check engine light is on it could be a variety of things including but not limited to the o2 sensor, throttle positioning sensor, and the MAF and MAP sensors. Best diagnosed by using an OBDII scanner to scan for codes. If no codes are present I would then check for the pressure coming from the fuel pump to make sure it is still functioning.

Hey Jruthesq

The 850 is equipped with an Idle Air Control Valve (IACV) which supplies the engine with air when idleing (a necessity since the main throttle body valve is completely closed when no throttle is applied, thus the engine would lack air without the IACV when idleing). The IACV is suspended in a rubber mount on the front of the throttle body itself, and is easily removed and inspected/cleaned. If it's dead a good cleaning usually gets it going again. Also make sure that the air from the IACV is unhindered on its way from the IACV to the throttle body (it's actually common for the holes in the throttle body to be gunked up so bad by hardened carbon deposits that one sometimes needs a nail or even a drill to open it up again).

Just thought I'd mention this since you said that the gas needs to be feathered for the engine to start. When you press down on the gas the main valve in the throttle body opens up, closing the IACV and supplying the engine with enough air.

Oh and if your fuel pump relay is a green one marked 103 you should replace it with the new and improved red one. The relay is located under the fuse box cover under the hood. Remove the 4 torx srews holding the cover in place and you'll see the relays under there.

Good luck mate!

there might be a problem in your fuel line. try buying a can of sea foam [Red and white bottle.Available at any auto place. Around $9]. pouring about half in the tank and the other half thru a line in your brake booster or another vacuum line. the line will be under the hood to the very top right. it should be black, round, and two lines coming out of it. do this with the car running so maybe have someone else hold the gas to about 1500 RPM. Slowly drip the sea foam in until it almost dies then put your thumb on the line to keep it running. keep doing that until the can is almost or fully empty. Let the car sit for about 5 mionutes then start the car and keep the RPMs to about 2 grand. There will be smoke fromt the exhaust SO DONT WORRY! Just keep on the gas until the smokes clears. If that doesnt help let me know!
