Thanks for the reply. Yes the code is e30.Today i got the car put back together got gas in it and got it to start still with no power it will start right up everytime but it didnt like to run. I ran it for probably 30 seconds or so and the whole exhaust before my cat was hot and air putts out of the tail pipe. I do not have a factory service manual all i have is a haynes. The only thing i have not tested is the ignition control module which appeared to be newer the pick up coil (Im getting good spark on all cylinders) and the map sensor. I need to know how to test the map sensor is this something autozone can do? Can i unplug when the car is running and it should die or something? When the car started to run badly i could smell gas strong and i was getting about 4 miles to the gallon on the highway. I am guessing that the o2 sensor broke off and caused an bad fuel mixture which may have caused my catalytic converter to fail i drove probably 100 miles or more dumping gas. I plan to buy a new o2 sensor if that doesnt do it i am going to unbolt and drop exhaust before the cat and see if thats my problem. Am i going the right way with this? Should i do something else first? Why am i not getting codes for these things?comments appreciated thanks
