Good start on the typical items. Two things more that you can check:
- Is it your CAI that is causing the misfire/rich condition? Most of them can give problems like that - Compression test, coolant test for combustion gasses, and oil test for coolant. |

Care to elaborate, just curious as to why a CAI would cause a rich situation?
He didn't say what brand, so I was leaving it open as an option it could be. Some crappy intakes out there. |
Wasn't aware of any CAI out their that had smaller diameter than stock, regardless good to know.
I only ask because my car is running slightly rich. |
Yeah, I'm not specifically aware of any either, but well... I imagine they exist, especially on ebay.
|
3p I.D for the CAI
250ml per tank for the premix |
You really made me convert that :slap:
Also its about twice as much as it should be. |
Hmm
Rich will foul plugs. Fouled plugs will cause misfire... Vacuum leak will make it run lean, not rich. Dirty injector that is not closing? Run a can of injector cleaner through the tank? I like Lucas, but it depends on what they have where you are. 20 petal stomp after all the work you did? |
No vacum leak
20 stomp brake pedal with the oil gauge confirm the reset plug clean and new new coil new wire i try injector cleanor in the fuel no change and today New cel p2097 with my old p0300 p0172 One day..... One day i will find my problem :boink: |
I'm thinking it's the 02 Sensor. If everything was running right I would not suspect the CAI.
Try unplugging the Front 02/lambda Sensor and seeing how it runs. |
what is the diameter of the pipe to the stock airbox or a good cai
with all your opion im nervous with my custom cai (is not a cheap job tig welded good 3 ply cuppler t-clamp) but in 3In I.D |
tomorow i try the o2 , i have nothing to lose .... 1 month and i find anyting XD but i make a big tune up and a read a lot for try to solve my problem
my Mazda bpT Gtr megasquirt miss meee fuck that was so easy XD . |
3.375" Stock MAF ID
|
I had the same P0172 code and discovered that the nipple on the throttle body that's supposed to be plugged when a CAI is installed wasn't plugged. The plug had come off somehow. (Maybe I did it when I changed the plug wires.)
Also, smell the oil on your dipstick. Does it smell of gasoline? If so, you should do an oil change. |
i bet for the cai , anyone have a Aem for sale and ship to canada XD
|
Im gonna burn the car........ a put stock oem box & my car run like shit but i have no more cell for missfire etcc the only i got po171 run to rich
