some of you know I have a 90 2.2 that is boosted (check my registry which is not quite updated but)
aight just got a 2 bar map sensor today and installed it since I have boost, apperantly I am retarted or something and hooked it up just fine but went to start it and did not want to stay running at all, noticed that there what looked like fuel dumping out of the tail pipe, now the volt idiot light is on, so I went to change it back to my original 1 bar map sensor and it appears to run fine, but the volt gauge is still lit up. whats up? is the first question. second question I thought by running boost I may have needed the 2BAR, yes or no? and if so what needs to be done so I can run it safly with out any pain in the ass time on keeping it running?"

any help would be good

Thanks

Put your stock sensor back in. The 2Bar is not going to work for you. The PCM only understands a 0-5V reference. The values for the sensors are different and the PCM does not understand the difference. It sees the voltage and commands what it is calibrated for(the 1bar sensor)....

yeah I did that so I'm going to keep the stock sensor. would that have anything to do NOW with the volt light being on or possibly triped anything? I guess since its my car I'm more paranoid.

I'm not going to pretend I know anything at all, but half the time once a light goes on, even if the problem is corrected, the light will stay on again until the car runs the monitors to see if anything is wrong or not. If it appears to be running fine, drive it around for 50-75 miles or so, and it should shut off if nothing is wrong.
