Hey Chris thanks a ton man, i'm going to grab the codes from it tonight after work and then i'll post them up here. I'll take a look at the map and i'm sure a new 02 sensor wouldn't hurt, i think the one in there is the original and has been though alot of tuning in the past.

ok guys heres the codes for ya, i havent had a chance to look them up yet but here are the numbers
P0137
p0125
I was actually kinda surprised it only threw 2 codes, but apparently these are the ones that make it run like ass
"Horsepower is the Ultimate Accessory"
the codes aren't making it run like ass, whatevers causing it to throw the codes is probably making it run like ass. I still can't believe so many people don't invest in a cheap code reader when doing fairly serious mods... of course i'm guilty too i didn't get the scantool for mine until long after i was running low 14's, but now after having it I can't believe I ever lived without it.
According to my google search, P0137 is a downstream O2 sensor code.... does the car have a cat?
P0125 is an ECT code... Inssufficient coolant temperature for closed loop mode... this is your problem right here 100%. Remember that just because it is throwing a code that mentions a sensor by name, it DOES NOT necessarily mean the sensor is bad. It could be a break in one of the wires to the sensor, corrosion in the connector, a loose ground, etc... It could also be that the engine isn't getting up to temp, perhaps the thermostat is stuck open? I've seen it happen lots of times on Dodges when I worked as a tech for them, typically the thermo had fallen apart inside the housing and wasn't blocking the flow of coolant. I'd make sure the temp sensor is plugged in securely, if it its, I'd say check the thermo... Not sure how hard it is to get to on a 2.4 but i'd be willing to bet thats your problem, if its a new ECT.

thanks for the help Scarab, I actually do have a scan tool, or I did but it is currently not working (Snap on owes me a new one) Anyways thats why i ran it to autozone just to get the codes and see what the issue was. The car does not have a cat on it, but it also does not have a rear 02 sensor, that is where i have my 02 sim plugged in and also im using the rear bung for the wideband. I will look at the ECT wiring, connector, and sensor itself tonight, then grab a new thermo and throw it in, it's not that difficult on the 2.4. Thanks for the help so far everyone, technology is great when it works and frustrating as hell when it doesn't.

ok this makes absolutely no sense to me... I bought a new ECT sensor, installed it, and started the car up, the car idles very irradically and was rich. When taking off the car hesitates and feel like its cutting out. Once the car is warmed up it runs perfectly fine, but everytime i shut it off and restart it i have this same issue with the idle WTF? The car actually ran better when i put the old sensor back in the car

anyone have any ideas???

Weird, I'm having the same problem with my '99 Cav Z24 with the GM S/C. The CEL is on, but I haven't had a chance to check to see what the code(s) are. I will check on Monday and see if mine are the same.
