HELP!! my 95 Eclipse GST backfires at 4500

[boosted954g63]

I need a little help with my 1995 Eclipse GST. I was driving today and out of no where it backfired at 4500 and produced a tint of blue in the exhaust fumes. So I took it easy on the way home and once I got home I started to try find out what was going on with it and I figured out that it back fires only at 4500 RPM. 4500RPM is all it would rev up to, it would not go any higher or it would back fire. So I called my friend over with his OBD-II diagnostics toll and it came up with five errors (listed below).

#1 P0125 Exsesssive time to enter closed loop fuel control
#2 P0136 O2 sensor circut malfuntion
#3 P0141 O2 Sensor heater malfuntion
#4 P0335 CKP sensor circut malfuntion
#5 P1400 manifold differintial pressure sensor malfuntion


I have no clue what is going on. I need some help quick it is my only transportation to school. Also, I might add, that when my key was in the on position (with out my engine on) the ignition coil was ticking. Some help would be GREATLY Appreciated.

Also is it ok for me to drive, i need to know please!!

Thanks Nick

I still need help I ordered an O2 sensor but the stupid people at the local auto parts store ordered the wrong one. They said it should be here in two days. Now all the sudden it started to over heat and I saw that my radiator fan was not running. So I have to replace I believe is the coolant temperature switch. So I still need help to find out what is wrong with my backfire problem if the O2 sensor does not work. Please help me I really need the help, am desperate.

Thanks Nick

well at this point we can't help you. Update us when u have the o2 sensor installed. It all might as well be tied to the o2 sensor.....


o2 motinotrs to a/f ratio...

[boosted954g63]

Ya they are idots. I whent up there to get it and they were waiting for me to come in and the guy handed me the part and told me to check it to see it was the right part. It was the right one so i put it back on the table and the guy pick it up and said "Your good to go" and i walked out saying thank you with the FREE O2 sensor that i ordered. The stupid guy forgot to ring me up hahaha. I got the O2 sensor but i have to put it in tonight. So ill post back tonight to see whats happning.
