    truck starts easy but after its running until the motor is warm it idols irregularly and its worse when the outside temp is cold too. when the outside temp is cold too it will stall out when you put it in gear. the check engine light isnt on so im guessing a vacuum line is bad but i cant find a diagram. can you help me?

Pull the distributor. Check the gear on the bottom of it. Replace a bunch of them for wear. Causes no power and bad timing. Depending on wear. Replace the gear or the distributor.

I can almost guarantee the engine coolant temperature sensor is faulty or very dirty. You will find it on the top of the intake manifold, just beside the thermostat or upper rad hose housing. It is a 2 wire sensor, brass. It can be removed with a 3/4" or 19mm deep socket. It is the primary input to the engine computer before the O2 sensors take control (after engine warms up). Don't attempt to remove when hot or under pressure, refill and bleed after. You will notice a huge difference to fuel economy.

97 Chevy Tahoe is hard to start , problem is worse


This is just a guess- but I would try changing out the coolant temp sensor- this tells the computer that the engine is cold and needs a bit more fuel to start. If this is happening even when warm- look for a vacum leak.

1998 Catera will not start if it sits overnight in cold weather


It can be worn distributor cap/rotor or coolant temperature sensor.
To check it leave car outside, try to activate if it is not use the hair fan and worm up the distributor cap area
http://www.autozone.com/Ntt,distributor%20cap/shopping/allResults.htm
If it helps replace the distributor cap/wiring/spark plugs. If it doesnot help warm up the coolant temperature sensor:
http://www.autozone.com/shopping/repairGuide.htm?pageId=0900c15280090338
and, if no help, spurk plug area.
Also good idea in cold weather use higher octane fuel or regular with octane booster or injectror cleaner added and ask the mechenic to put winter oil (less viscous) for winter time during oil change.
Good Luck
