so in the past i bought a jet chip, installed it and messed my car up, took it to the dealer and then they gave me a new ecm or ecu(IDK) when i drive around my engine light will come on. then after awhile it will turn back off. i disconnected the battery that got rid of it, but then it came back on. it seems to come on when i race some one or just doing a couple of pulls. i do have a k&n intake and i did clean it, do u think that mas flow sensor is plugged??? i read that kn can do this so help out if u can. AND YES I NOW I CANT SPELL WORTH A ****

 

Get some electrical parts cleaner and try cleaning the MAF.

 

DO NOT USE ELECTRICAL PARTS CLEANER ON THE MAF!!!

They make mass airflow cleaner by CRC use it.... it works great! And it's not from the K&N filter it is from OVER OILING it!

 

ya thats what i was thinking will is there any place in my town that has something i have a autozone napa and wal mart lol

 

EP cleaner does nothing. Trust me it's completely safe. Read the label, and we use it on all our PLC's and Drives at work.

Auto parts store would be best, you can get EP cleaner but MAF cleaner is better just because it says it's for MAF....

 

is your car and auto or manual?

Auto have no idea...
but
If its a manual the it could be the clutch sensor(s)...

I had a similar problem and my car went to the dealer 4 times before they could fix... if they did fix it, i think they just pulled the check engine light fuse to be honest...

 

I've heard of people having problems with crank shaft position sensors.

 

ya mines standard

 

next time the light pops on go down to auto zone and have them read it (they'll do it for free). if it comes back as bank one rich or lean condition etc. then it's your MAF. I think the code is P0171. Go back inside and buy the CRC mas air flow sensor cleaner. It's only like 5 bucks

 

ya i went and bought that crc stuff and after i cleaned it i did a couple of pulls and so far so good.

 

Invest in a small code reader -- you can get one for around $50 that has an erase feature. Check them out a autozone or other parts house. Thta way when you get a CEL you can find out what it is for on-the-spot

 

Last time I asked them to pull a code it wouldn't connect.
