I posted a thread not to long ago about how bad my fuel economy was (about 12-13MPG). Aside from the poor mileage, the car idles and runs perfectly. I finally pulled some codes tonight. The KOEO test said 111 'passed'. Then I did a KOER test and got 137 and 173, both of those said "HEGO 02 sensor always rich".
Assuming the car is always running rich might explain why it cranks on a restart after making a stop because it is running too rich and possibly flooding the engine. After seeing these codes, it further confirms my previous thought on replacing the O2 sensors. I will do that soon and repost. If that doesn't help any I guess at that point I will just be screwed.
