Stop ignoring your CEL, you cruel bastards

you mean they're lights other than handbrake, door and high beams!?
dude... mind blown.

I know that feels

Smoke the exhaust. I've seen cracked manifolds cause lean codes before.

Thanks, I'm too much of a pussy to dump fog into my exhaust but I'll bitch harder about checking for that next time I take it in

>rx8
>permanent cel from a gutted cat

I'm not paying 1k for a piece of emissions equipment in a state with no testing.

my egr valves has some kind of malfunction
i think it's the sensor since the valve itself is working fine but they're not separable
so i just let it on

I know exactly what the problem is with causing my cel light to illuminate. I just dont habe 800 bux to spend to buy new injectors.

Tfw my car has an SU carb and points ignition
I have no check engine light but if I did it would have so many fault codes. Poor thing.

>CEL has never come on in 327,000km

Who cares if it's still running just do what you know you can do and don't worry about the rest. Warning lights are just a Jewish trick to get you into the dealership for """diagnostic""" tests, so they can refer to some Jewish manual that tells them to replace five parts instead of fixing one.

>p0015
>replace vvt sprocket and solenoid
i'd rather just change my oil and clear the code

>>replace vvt sprocket and solenoid

lol fuk just LS swap it bruh

>might be buying a Fiat 124 Spider soon
I can't wait to enjoy time together with my engine

I don't even have a computer in my truck let alone a CEL. Shit just stops working :/

My Saab is full of codes. Everything I fix just breaks again within 2 months, the parts are garbage.

>Fiat
You should just invest in a cel scanner

Nah fuck that, im having a pretty fun time with power steering being borked right now

help me i am in hell i just want my vehicle to run correctly

I don't feel like doing my intake manifold and throttle body

my ABS and TCS lights came on and won't go away, but i've given my wheels n brakes hugs :(

bmw maintenance is easy

i got my car at 80k km, 92k km now after a year. When do i see my first CEL

>having a CEL

I bet you have fuel injection too

They make rebuild kits for those pieces of shit?

my egr causes a check engine when the car warms up, presumably when the egr should close
at the very least, it lets me know what i reach a good operating temp in winter

>Daily driven 1997 M3
>227k miles
>CEL hasn't been on in over a year

Maintenance, faggots

I found out the reset for my check engine light, the manufacturer cant fool me! The check engine light on modern vehicles is like a slot machine, you may or may not have engine problems but you end up spending a lot of money for nothing in return. I know for the 2014 dodge 1500 its 1. Hold down key in start position but don't turn on truck, 2. Press brake and accelerator pedal two times each. Boom done. Yaint foolin me!

how am i not surprised that a 2014 chrysler already has a CEL

>resetting your CEL without fixing the issue

get a new o2 connector with pigtail and soldier it on.

the wires have been torn off inside the o2 sensor, inside the metal housing. no way to solder and get a solid connecttion

Do you know what the code was? The rear o2 shouldn't affect mileage, it's only for checking cat efficiency. Maybe the front o2?

oh thought you meant from off the chassis harness, get a new sensor then.

several codes actually:

P0132
P0135
P0138

It doesn't like the readings from either O2 sensor and the front one's heater is out. Replace both o2 sensors.

>cel and power drop
>plug laptop into shitbox
>knock sensor
>no noticeable knock
>realise that the slowing down crackle in my extractors is firing knock sensor
Wat do?

Figure out the resistance your knock sensor has normally, chop it off and solder in the equivalent resistor

W-wat if I get a real knock?

Better keep good high octane gas in it senpai

>Code 43
it could be literally anything or fucking nothing

What car?

...

90 - 97 OBD1 honda

>fuel filter
>02 sensor
>intake manifold vacuum lines
>gas cap is loose

Pick one and get started.

>>fuel filter
done, changed
sensor
done, changed
>>intake manifold vacuum lines
checked, all brand new
>>gas cap is loose
lol
>>fuel injectors
done, new injectors
>>fuel pump
done, along with a new tank

only thing left i can think is the downstream o2 or the sending unit.

>one day car has very rough idle
>but no CEL so I ignore it
>rough idle hasn't gone away

All it needed was a new ignition coil and the problem was fixed

>gas cap is loose
>lol

I'm serious, could also be a bad cap, they do eventually fail to seal and cause pressure to escape,

i've got a (new) oem cap from hondurr, believe me i've checked that more than a few times thinking the same thing as you.

Ecu could do it too.

>o2 Sensor
I don't know man, seems like a waste of money to me.

My other 3 cars don't have CEL's so I have no idea if somethings wrong. Nothing feels wrong.

hey thats my car glad to see someone liked my mem

excellent mem friend
I intend to post it many more times

did engine died?

rip

Replace your thermostat

CEL

Been running literally perfect

Plug to check

"Weak" spark on 6

Glares

Same here, brah. Still spooks all my friends when they ride with me.

I know that would fix it, but honestly, it's only happened once when it was like ten degrees out and I can't be bothered until it doesn't get up to temp when it's warm out.

there is a CEL on the car atm but that money is going to a vacation to somewhere in mid march

>tfw overly obsessed engine
VW life

Weird. My exhaust mani is split large enough to sound retarded on my Envoy and it's not giving any errors

Stop buying shit parts?
Stay away from the chinese made and stick to the Swedish OEM parts.

what's a CEL

toyota?

Just replaced my alternator in the parking lot of Veeky Forumsreillys today. Had the dude run the reader after I got it running and let it sit for 10 minutes or so, no codes to report. Feels good man.

this. I bet he's gonna say he gives a fuck about his wife next

>cel
>he doesnt have a 1980s diesel where basically nothing can go wrong

my CEL only comes on when im a fucking retard and leave something unplugged in the engine bay
