    I have a 96 Tacoma 5 speed with the 2.4l just over 200,000 miles on it. Most of the time it runs and drives great. Then bam all of a sudden it starts running like crap with this weird misfire. It's like it goes into limp mode or something. It typically only does it after it's up to operating temp but besides that no rhyme or reason to when or why. All last week it didnt do it once now in the past night and a half it's done it three times. Only thing that has changed since that is I got a bunch if stuff behind my seat right now where last week i didn't have but two things maybe. I noticed one time while it was running bad I could smell a ton of gas when I stopped at a stop sign. It also messes with my ecu because I have a code reader that has a tach gauge and a bunch if stuff I use while driving but as soon as this problem starts it disconnects from the ecu. I've tried multiple code readers while it was running bad and not one would connect. the only code that the truck has on it currently is p0304 I believe it is. It's a catalyst converter code because the previous owner cut it out. While driving it when it starts this problem the less gas I give it the faster it accelerates, the more I push the gas it bogs down hard. And in every gear you can only go so far in the rpm range and it's like it hits a wall. The last thing that is consistent with this problem is that my a/c stops blowing cold like its kicked the compressor off. The only thing I have being able to come up with that it could be is the up stream o2 sensor going bad or wires that are cracked/arcing maybe. Because I was told that o2 sensor deals with the fuel tanks on this model tacoma. Thank you for any and all comments in advance. I will be checking this thread multiple times a day. If anyone needs more info feel free to ask but that's about all I can think of right now.
