my check engine light came on when I hit 60 mph but then disappeared. next day driving I hit 60 mph again the light came on again but this time it stayed on. the car seems to be driving normal but I want to know why the check engine light is on and if it's going to be a problem. please respond I need help!

 

take it to a parts store and ask for a code reading--its free
report back the letter number combination found

more info like year miles anything else acting up will help figure out the problem

 

will do .. thanks

 

were you doing anything strange like 2nd gear 60 mph?
or minding you own business in D5 cruising... or getting on freeway??

 

exactly what you said .. doing 60 on d2 . the codes that came up were p0301 p0305 p0300 p1399 .. is there anything I can do without taking it to my mechanic?

 

google the codes, stop driving in a way that overheats the cat

 

the p03xx codes are misfire codes. i just encountered a similiar issue. a new ignition coil fixed the problem.

this'll help you out...

ok I will check it out .. thanks for the help.

 

I was thinking the single coil failure.. causes multi cyl misfire
Done a spark plug change recently?

there are several threads on this subject and ways to test which coil.. if thats the prob

 

I recently bought the car last week so idk what I have to change .. hopefully nothin major

 

its most likely 1 coil is failing,the other threads will guide you thru how to find which one
Buy a coil from parts store- about 50 bucks

whats the cars mileage now?
ckd any other parts like spark plugs to see if they have ever been replaced?

do NOT drive in SS mode of the trans at 60 in 2nd,,thats going to cause probs with the trans at the least
thats got to be close to redline,,ok to go there and shift up, but sustained high rpm lower gears is not ok

 

until you learn the secrets of the cars operation-and trans issues..
leave the trans in normal D5 mode..right side of shifter..let the car drive itself,, easy on everything~

 

ok thanks for the advice .. the car is recently at less than 92k

 

I bet it has the original plugs since the book allows them to go to 105 but the reality is the car runs better with new ones after 60-70kmiles
So thats one thing to consider,,if they are toast they can generate a misfire code
use NGK Iridium, iridium IX or platinum
car came with plats but gen3 has irids and we can use them as an upgrade in quality of plug--about 8 bucks each

are you on 91 octane gas ONLY,,or 94 if thats what is premium in your area

congrats on your purchase!

 

my suggestion is remove a front plug and inspect for wear
replace them, run seafoam thru the tank and manifold
and do the coil test procedures

note- reset ECU after you find a dead coil,.remove the `CLOCK fuse` on passenger end of dash for 1 minute,,that forces a master reset and system test..like pulling the plug from the wall on your home PC
It clears all the codes so you start fresh on diagnostics to see if its fixed

we will get you thru this no sweat and make your baby purr

 

hint: if you are pulling the plugs to replace--the wet or dirty one is the failed coil

 

trick seen on nascar to find dead cylinder:
touch a crayon to the header outlet from manifold
where it doesnt melt --is the cold cyl!!

if you own an infrared temp sensor-guage, the cold pipe is the one

 

thanks alot I will look into all of that .. I'm actually on plus which is 89 octane gas should I be using premium?

 

Yes

 

I just got my TL almost two weeks ago and I didn't know you could get all that background info. Thanks for the info
