Can a cracked exhaust manifold give these symptoms?
I'm getting erratic idle when the car is warm and is idleing more than 25-30 seconds. I also get a P0172 code (system too rich bank 1). The car also seems to lack in power in low rpm's. Narrow band A/F indicated a rich condition also...
I brought the car to the dealer and I at first thought that the EGR was bad. The apparently checked it and it's fine. The told me that the ECT (engine coolant temp sensor) was fked so I changed it with no result.
Mods are: Unichip (stock map), 2.5 inch exhaust w/ cat, injen, Boost sciences diverter valve connected on the brake booster line, hard pipes, colder plugs, custom msp smic, greddy EBC (not connected due to visit to dealer...)
