99 auto integra help needed badly
I have a 99 auto integra with a p1106 code. Barometric pressure
I replaced cat and ecu. Still throwing code. When I mash gas to the floor it bogs and accelerated really slowly and won't go last around 4k rpm unless I downshift to third. I dunno what else to check I'm very frustrated.

Re: 99 auto integra help needed badly
Check the MAP sensor. Most of the Honda ECUs have a barometric pressure sensor built into the ECU itself, and you've replaced the ECU so that is obviously not the problem. But, some engine management strategies compare the barometric pressure sensor reading with the MAP sensor reading before engine startup (the MAP sensor reads ambient pressure when the engine isn't running). So it's possible that you actually have a MAP sensor problem. I'm not sure if that's something that Honda does as part of their engine management strategy, but it's worth checking the MAP sensor to see what you find.

If it doesn't work, check the wiring also. It doesn't matter what condition the sensor is in if the wiring is broken or otherwise faulty.

Re: 99 auto integra help needed badly
i switched it just now. drives the same.
cliff's notes... barometric pressure code p1106
replaced: ecu, MAP sensor, catalytic converter...
did not replace TPS, should I do that even tho it's not throwing a tps code? Also, i did replace the throttle body at one point so is it possible that the code or no passing gear kicking in when i mash the gas is because the auto tranny cable is out of adjustment? i mean everything else seems to shift fine so I don't get it. I'm really lost on this one... anymore help would really be appreciated, it's like my car has a ghost I can't see lol

Re: 99 auto integra help needed badly
Hmmm. I don't ever touch auto tranny cars, so you're on your own for the transmission problem. Did you replace the throttle body gasket when you replaced the throttle body? I'm trying to think if there is anything that would cause a strange baro code having to do with a manifold or throttle body leak. I've heard of some people getting baro codes when they have filter blockages and vac leaks, but I've never experienced that personally so I can't really say if that could cause the problem you're having.
