Hey guys I have a 92 acura integra ls, manual, 1.8L.After 30 mins of driving holding a constant speed the engine will begin to feel like it is binding or bucking intermitently. After this as long as your driving the car the problem is frequent as a couple times every few min.I do have a check engine light (code 13) which indicates barometric pressure sensor. Is this my problem or does anybody think it's something else? let me know Thanks alot for any info.

only thing you can do is to go to a junkyard and rip a sensor out of one of their cars and put it in yours. Reset your ecu and give it a try. That should fix your problem. if not, let me know.good luck

Hey, turns out it was bad gas. Corrosion in the tank. It seems you cant run a car off of brown gas. A new fuel tank solved the problem. The baro sensor is still giving code, but the car runs fine. The baro sensor is hardwired into the ecu, so guess I'll get one when I get around to it. Thanks copyguy. See ya.

thanks for responding back with fix. Dirty gas? who would have thought!
