Hi friends...

Came from work yesterday night, and I noticed a hard down shift hit when braking, when the car is almost stopped at traffic lights. Check engine light came on. Scanned the car on morning having code 34 (MAP/MAF Low voltage). Checked the electrical plug, and vacuum hose at the map sensor, and they were fine, so I erased the code. But when I was just leaving to go to work, the car started to accelerate until it stopped off. Started but it dies when I accelerated. Check engine's on again. Tonight code 34 is present again with code 35 (IAC) too. With the car in park the engine accelerates from 1000 to 2300 RPMs, stays there for a while then came down to 1360, and stumbles. If I try to hit the pedal it turns off. Some times accelerates sometimes not... What IAC means? Any help or comment before I buy a new MAP?
