A tune up is basically have the oil changed, spark plugs changed, and have a mechanic look over the engine and suspension to make sure its alright. No air, isn't a big deal, but the idling is kinda bad.

 

Oh hell no... Please tell me she DID NOT just ask that!
Im sorry... I'll shut up now.

 

thanks

not every girl would know exactly what a tune up consists of. damm there are some guys that dont know.. so it wasnt exactly comedy central

 

Your car is actually a very nice one. All it needs is some care. I dont recommend you take it to any shops to have repaired... Try to make some friends who know a little about cars and can help you fix it yourself. If you take it to a shop they will definitely rip you off, especially since you asked what a tune up was. I dont know if resetting the ECU will do anything but have you tried that for the idle problem? As far as the PO421 and PO135 codes go those are probably issues with the headers and exhaust which can be fixed.

 

thanks for telling me what a tune up is and not for making too much fun of me, and for all of the usfull information you guys gave me, you guys are really helpfull, I would be lost if it wasnt for these forums and paying some mechnic big $$$


Question someone at school told me that if my car runs lean that one of my pistols or something like that will explode or something like that is this true? and is it just me or that search thing doesnt work anymore?

 

The piston won't explode, it'll melt. My car ran lean after I incorrectly installed an intake manifold (must have had a leak) and I ended up replacing a sensor, all the spark plugs, 4 valves, all the pistons and piston rings, and had to have my block bored. Basically, on the stock motor lean is very very bad.

 

guess I will stop driving the car till that cel elminator comes in

 

You shouldn't be running lean with the mods you have.

 

but, for the check engine light .. it says

PO421 Warm Up Catalyst

PO171 System Too Lean (Bank 1)

PO135 O2 Sensor Heater Malcunction

does PO171 mean Im running lean or something else then?

man that sucks that ECU messed up your car like that because of a little leak..

 

I think the PO171 code means you're running lean in cylinder 1, but I'm not too sure whats causing it. The header definitely isn't causing it, since thats on the other side of the engine, it might be the chip or piggyback that doing that.

 

I have no clue whats goin on in there, but it looks like its missing a 4G63 or two.

 

Its missing an evo engine and thats causing it to run lean? Never heard of that before.

 

I remember John Slow ES saying this. did some research on the web there are some cases which match up to what he said.. not sure will find out when I get the CEl elminator.. and maybe a new O2 sensor

 

The P0171 code is a bad O2 sensor code according to what I was told and what I have researched here on Evom. The auto parts store told me the same thing.

There isn't much info about it in Lancer forums but if you search the Evo forum you pull up all kinds of codes.

WADAD

 

I've bought two cars on ebay for my parents so I don't agree with you on that at all.
