I had a similiar problem with mines. Turned out to be the gas cap. After replacing it, I had no more problems. Hope it's nothing big

 

holy crap i have never seen you post.
good to see its a useful one

 

back to the topic at hand. Its really hard to diagnose anything without first pulling the codes. After you do that, we'll be able to tell you what it is.

When my egr started on the fritz (still is) i started pulling codes every couple hundred miles.

but again its hard to say anything until codes are pulled

 

Tell us your codes and we will tell u ur problems!!

Peace,
Jonny

 

thanks everyone how do i pull the codes, i know its a dumb question, i mean do i jump wires on the diagnostic terminal under the dash? if yes can anyone tell me in which port exactly i have to jump wires? any help would be appreciated

 

in the engine bay youll find the diagnostics port (not sure where since its an sc4), but jumper ports T1 and TE1.

I believe thats it, they will be diagonally right next to each other. Someone else please confirm this.

 

sorry i dont have a manual if anyone can post pics or tutorial that would be helpful

thanks

 

thanks alot man i am going to pull the codes tomorrow during the day and post the results

appreciate your help people

 

i just jumped the wires for the check engine light, light flashed twice and then big pause and then one flash, so does that mean code 21?

let me know thanks

 

ouch...
Code 21:
OXYGEN SENSOR SIGNAL/OXYGEN SENSOR HEATER SIGNAL
OPEN OR SHORT IN OXYGEN SENSOR OR OXYGEN SENSOR SIGNAL

good news is its probably an easy fix...bad news is the o2 sensors can be a little pricey

 

should i just replace the main sensor on the exhaust manifold? and if yes where can i buy one at fair price

thanks

 

means the ecu isnt getting signal from the o2 sensor. It may be all clogged up and burnt out that its just not producing the same voltage anymore.
