Hello
I got a 2003 acura tl-s. Last week I got a cel and they were

p0300, p0301, p0302, p0304, p0305. I thought that they were

a spark plug problem and I change them 3 days ago and today

they turned on again with the same codes. what else do I need to change? ignitor coil? plz give me some advice?
(btw, the car doesn't show any problem. No vibration, no rough idle)

one more question.. can I use a aftermarket coil pack? the genuine one is so expensive


thank you for your advice

01tl4tl

are those the random or multi misfire codes?
thats usually a bad coil on 1 cylinder= ok to use aftermarket coils no sweat-
its done every week by someone on here~

what did you use for spark plugs- the TL is very picky
use ONLY NGK Iridium or NGK Platinum- or denso brand but they cost more and last fewer miles
If the parts store sold you ac delco or bosch- take them back and yell at them for selling non approved plug!!

did you reset the ECU by pulling the CLOCK fuse on passenger end of dash for a minute?

drive it after that and get codes read again
