My idle is a little rough, but after using the search function extensively, I'm really thinking MAP sensor. The problems i've noticed only seam to occur when my CEL is on. The keydance reveals codes 12,13,55. 13 says map sensor and i have been experiencing a fuel cut or something of the sort at 4k rpms and a few other symptoms shared by others with map sensor problems. I plan on trying to replace the sensor this weeekend, but wondered if anything else could be causing the sensor to read incorrectly (such as vacuum leak or something???). The wierd part is that the CEL only comes on if I let the car die at a stop light or something, which happens everytime if I dont keep my foot on the gas to keep my idle at around 900 rpms. I know i need to fix the idle or whatever so that i don't have to rev it up while I'm stopped, but why would killing it cause the cel 13? Is there another underlying problem that I'm missing?

---Harry. My car topped out at 140 this morning. I need "turvo." Two of 'em. And Harry, I need the glue to be dry by tonight.---
