Lol a year? Too lazy to reset or what? Lol

No just didn't have money to replace 2nd o2 sensor then when I did it threw the code for the precat and I didn't have time to do the nonfouler for 3 or 4 months so ya it was about a year. Snd it wasn't because I was too lazy just too poor

I hear you I'm a broke ass college kid lol

So I threw a check engine light the other day. The code was cylinder 3 misfire. Any ideas anyone?

I put im NGK G-power plugs about 4000 miles ago. So could it be the coil pack? Maybe boot?? Anyone else ever have this code?

could be anything - could be nothing.

 

[Jordysoso]

If it was nothing how would the code get thrown? I could see once but the check engine light coming on twice in a month is kinda odd. Even after an ECU reset

 

[njaremka]

if the problem was never fixed, resetting the ecu won't change anything.

if the coils have never been replaced, get new ones - my suggestion: do both. same with the plug wires. try to eliminate anything ignition related that could cause any issues. then, go from there.

Recommendations on wires and coils? Should I replace coil boots too? I know NGK makes wires but is there anything else?

 

[njaremka]

get NGK wires, as those are stock for mazda. coils can be had at any parts house. its hit and miss if the coils come with the stub wires, but most places should have those available too. (if they dont come with the coils)

 

[Jordysoso]

Best places to buy? Can I stil drive the car without messing s*** up too bad?

 

[njaremka]

advance auto parts, auto zone, napa... where ever you can find a couple.

as for further damage, if the car keeps missfiring, you can damage the cat from too much fuel going into it.

 

[Jordysoso]

Well the light came on yesterday. How long u think I got before the cat is shot?

 

[Jordysoso]

ok im ordering NGK plug wires, and do i have any other cheap and cost-effective options besides BWD for coils? Duralast?

 

[njaremka]

coils are coils when it comes to the protege. just get something to replace them.

Ight I threw on some NGK wires and BWD coils. Thank you advanced auto for the free overnight from Delaware
