hi everyone. my wife has an 04 G35 coupe. she drives alot of miles everyday for work and she is VERY late on an oil change..yesterday she went to the mall and it was no problem. when she went to leave the mall the car turned on and then turned off. after a couple times of doing this and pumping the gas it would stay on. then this morning she was on her way to her fathers house it was a bit worse. it would turn off when she would come to a complete stop.. last night i checked the oil and it was low so i went to the store and dropped in 2 quarts of oil and it turned on no problem and stayed on. her dad took her car today so she can drive without a problem but he told her that her check engine light came on today..i havent taken it to check what the code is but you guys have any suggestions in the meantime?

thanks

 

Routine maintenence is key...

 

Define "very late"...

I bought a low mileage 10-yr old Prelude only to find out the previous owner didn't know you had to change oil... Before too long my copper crankshaft bearings were torn apart and ended up in my oil pan

 

no no not that bad i promise..but id say about 5000 miles or so over....she told me she took care of it and got caught in her own lie...when i checked the dipstick it was fairly dry and had a lot of sludge on it..

 

wow sludge on the dipstick??? were you using fully synthetic of just regular 10w30 oil???

 

regular 10w30. she bought the car used and thats how it came. i want to change it to synthetic since she has high mileage on it. i went last night to go to AutoZone so they can run the test on it to see what codes it throws and the guy told me nobody there can help me cuz its too late outside and dark i was like oh come on im pratically dressed in a suit im not going to jack anyone lol..but regardless im taking it to the stealership today so i hope i can get this resolved..thanks for you help and if you have any more suggestions i will be checking!

 

thats funny autozone guys were scared to step outside.

 

Keep in mind that the G has a 5 quart capacity... if you were very low on oil, 2 quarts might not be enough, and might have been consumed already. If the car sounds and runs fine now, the service light might be a small leak somewhere... go get your car serviced now!

 

must have been a cheap suit.

change the oil ASAP using 5w-30 as recommended. Change it again in ~1000 miles to get the gunk out..

reset check engine liight

 

to be more specific the specs say 5 1/4 quarts of oil, lol.. so you would have to buy 6 quarts, juts to put that 1/4 in... anyway 5 quarts is good enough...

 

i did a couple of searches on here before i posted and i saw that people said 10w30 or 5w30..does it matter or do i just put 5w30 and not ask questions? lol..also how do i reset the check engine light?

 

ok well i got the oil change yesterday and the car didnt stall out on me. when i got home i reset the ECU and it started to stall again. the check engine light went away and has not returned. someone told me to clean the throttle body so i think im going to do that when i get home today..any other suggestions?

 

check intake filter.. make sure its not like super dirty or something is stuck in there.. how many miles on the coupe again??? did you change the spark plugs yet???

 

when they changed the oil i had them change the air filter..same thing right? also the car has 71XXX miles on her and i dont think i've had the spark plugs changed on them..i've only had the car for a year and a half since i bought it used so i dont know about that the previous owner has done..

 

yes the air filter is the same thing as what i said "intake" filter. If I can remember your supposed to change the spark plugs every 50,000 miles?? hopefully someone can correct if im wrong. Your spark plugs might need to be replace, after their replaced im sure you'll feel a difference
