Engineer starts but dies if foot taken off gas


This may be as simple as a bad idle air control valve, this valve controls the idle but if the engine is running rough or if there was a engine light on then you may have other problems, but if the engine is running good and not rough then i would say its a bad idle air control valve, this valve is located on the throtlebody and easy to replace, heres a picture of it.johnjohn2_59.jpg

When I accelorate my ac vent goes from center


Check the white vacuum hose going to your recirculation door outside under the hood. It is located on the passenger side firewall . The hose becomed brittle and falls apart. I get small vacuum hose and cut into the wiring harness to locate a good section of hose.Put hose to vacuum motor. Good luck.

Ca/heater controls **** in vent mode


Just fixed same problem with my '98 Jimmy for under $3. The vacuum line comes thru firewall (semi-rigid 3/32" hose) with the main wire bundle just below the brake powerbooster. After about 7" this line goes to the first 3-way 'T' connector with an inline adapter going up to 5-32". Hose 2 from the tee goes to connection on the inside of left front fender. Hose 3 from the tee goes to another 3-way fitting where the system gets vacuum ultimatley from a larger hose going to the plenum where the PCV hose attaches. Check ALL these hoses for rot or splits.
