Customer Question
Cel with p0301 with...

Cel with p0301 with rough idle and misfires. Good spark and wires. Delayed throttle signal being sent. Etv system. While smoke from exhaust. Runs smooth after 2000 rpm but shakes between 1000-2000 rpm. Haven’t checked for air leaks but hear air escaping and can’t find it.

Mechanic's Assistant: Does the light stay on, or does it blink?

Stays on

Mechanic's Assistant: What is the model of your '00 Mazda?

2011 I think sport but not 100%

Mechanic's Assistant: Are you fixing your vehicle yourself? What have you tried so far?

Yes. Cleared cat after major meltdown. Replaced o2 sensors, plugs, wires, full oil change. All fuses good.

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

I feel like it might be the barometric sensor but can’t find it. ( based on research)

Mazda Mechanic: EricFromCT, Auto Technician replied 8 months ago
White smoke is generally too much fuel. Have you tried swapping good the number one injector with a different one and see if the code changes cylinders?

Customer reply replied 8 months ago
That’ll be my next step once I check the e-shaft position sensor. To get to the injectors I’ll have to do it over the weekend. I’m military with little time to throw at this so a little work a day is all I can do. I’ll get back with you when I can give that a go.
Customer reply replied 8 months ago
FYI I had no coolant in the oil when I did the oil change. Have I eliminated a seal leak???
Mazda Mechanic: EricFromCT, Auto Technician replied 8 months ago
Technically you still could have a headgasket issue in that cylinder burning coolant. you can check that with a cylinder leakage test or a coolant pressure test.
You can get back to me later on. Note that after rating my assistance with the stars above the chat will still remain open so you can bookmark this page and come back with follow up questions.
