:help: Hi.. Yea its about a 92 grand caravan 3.3L. check engine light been on for a while. I looked around the forums for an answer already but not much luck. Go start start when vehicle is cold, dies right away. It wont go anywhere unless you put it into gear and go right after you start it. After driving it a bit it'll keep stalling getting ready to stop or after I just did. After temp gauage kets to almost half, it wont stall much. rpms fluctuate at idle. Lastly gas mileage is horrible and accel is non-existant.
came up with codes 14 and 51 from autozone.
I think it could be the set of 4 relays above driver wheel weel that connect to one object in back of bay. But thats i can think of thx for help

Code 14 means you have a bad MAP SENSOR, it is mounted w/ two bolts on the intake manifold near the throttle body and should run about $70 for the sensor.
Code 51 means that the fuel system is too lean, typically due to the bad MAP SENSOR.
Change out that sensor and let me know if it's better.

Yeah, i figured that was the first thing to try, i replaced it but not much help. Im wondering if it could be the wiring to the sensor itself, because it has alot of miles and the factory wiring.. alot of the protective covers on the wires under the hood have some damage.
The only other thing i could think it was is an electiral problem because of that. One day i bumped some of the wires, and i could hear it was running alot better, but didnt have enought time to see if the check engine light went off; it went back to the way it was after like 3 seconds, but i cant find that wire anymore lol.
Maybe ill find some1 to look at it, but the way its running i might want to play with the hammer on it :VHOT:
