Depends. Are we talking about tranny or engine?
My tranny gets funny in the cold. I let it warm up while i am still in the driveway (in gear) which seems to help. A key off/restart seesm to clear the limp mode and it works fine after that...
On cold days I have also been getting a 'too lean' code on the second O2 sensor (probably due to my mods, though )
My suggestion? Spend the $$ to get a code reader. I use it UH Lot on all my vehicles

I dont know if its the trans or the engine how can i tell? I have some mods also and i cleared the codes last night and there were a few codes, Cyl 1 misfire, o2, and something to do with fuel. I let my car warm up for about 5mins tried to pull up closer to the door and it went into limp mode not only once but 2-3 times. shut the key off for about 30 seconds and started it back up. It was idling at 2k (usally idles at 900) then i drove about 6 miles and shut it off at a stop sign after the six miles and started it back up and idle was back to 900 and it drove fine???????

1st stop clearing codes. freeze frame data and dtcs are the first place to start when you're having problems.
Also if you get a code reader get one that displays live data. You'll also need a multimeter.
If you want to pull codes from the TCM you need a better than generic scan tool.
I've never had the fuel relay problem, but if you suspect that it's bad measure voltage at the fuel pump, KOEO and KOER. if you don't see battery voltage swap the relay.

i'm using torque with my ralliart for check engine lights... so far i like it tells me what i need to know
if your getting a misfire code you've probably got a bad coil or spark plug...
pull it and have a look at it
easy way to test the coil is to move it to another cylinder, and see if the misfire code follows it then replace if it does... if it doesn't check your spark plug
