Did this problem come about all of a sudden or soon after you did something with your car? I'm having a simlar problem with my car and this is the feedback I've been getting. Read the whole thread, because there are multiple possibilities.

I think you're not getting answers because we need more information.

How many miles (kilometers) on the car?
Have you worked on it recently?
What have you checked so far?
When was the last time you cleaned the MAF?
Is it stock?
Is the tune stock?
Do you have any exhaust leaks?

**barryz** · 01-30-2011, 01:18 AM

oke sorry about that here is the information

How many miles (kilometers) on the car? 40.000 miles
Have you worked on it recently? changed the oil 4 months ago
What have you checked so far? don;t know where to start
When was the last time you cleaned the MAF? never actually
Is it stock? yes only borla catback exhaust
Is the tune stock? in did have a chip on the on the intake but took it of
Do you have any exhaust leaks? i don,t think so but when i drive it seems like making more noise from under the car and also the car has been standing still for 4 months and before i did not have no problem ...

thanks for thinking with me greetings barry

might wanna change the fuel filter, its only like ten bucks and its a easy yes or no to your prob, after that do plugs, wires, air filter, clean your MAF. these are all easy an semi cheap things to rule out.

fuel filter has been changed 5000 miles ago i am gonna change plugs and wires to start with this weekend !! greetings barry

+1 to this. Get some MAF cleaner at the auto parts and clean your MAF. Does your car has KN filter?

**barryz** · 02-02-2011, 01:49 AM

yes i have the knn filter

**2000dreambird** · 02-02-2011, 03:11 AM

throw it away K&N filters will put a oil film on your MAF, I had it happen to me...

cleaning the MAF is probably a good place to start. You can get MAF cleaner at pretty much any auto parts store here but I'm not sure about over there. It just to be a non-residue electrical cleaner. Take the MAF off and spray the 3 little resistors that are in the air stream. Don't touch those as they're very fragile.....just spray them off. It does sound like a fueling issue to me but could be a number of things. Do you have access to a data logger at all? I would also make sure you don't have any exhaust leaks before the front O2 sensors.
How does the car idle and run in general?

**barryz** · 02-02-2011, 07:19 AM

never had no problems before i just today changed the spark plugs they where never changed from looking at them i am the second owner so it was time for new ones seems to run a lot better i am gonna clean the maf sensor tomorrow and i am gonna order a new on soon is like a 300 dollar high performance maf sensor worth it??

thanks for the replys

**0rion** · 02-02-2011, 07:24 AM

no, just replace it with a stock one but make sure you need one at all first. Say it was running fine before the plug change? Have you made sure all the plug wires seated all the way on the plugs and coils? Did you remove the a.i.r. pipes to get to the plugs? Make sure those aren't leaking.

**JayTA98** · 02-02-2011, 09:49 AM

did you get new plug wires? If not, did you check them to make sure you don't have one or more that are bad? Like Orion said don't buy a MAF until you clean the current one and if it is bad just get the stock one.
