Everytime im not on the throttle or my cars in idle the car either idles very ruff(jumps between 300rpm and 800 rpm) or the car stalls out

I was told it was either a dirty fuel filter or a band TPS sensor,,

Can someone please clarify

 

It can be many things from the intake you are using to the tps...

Our cars dont have typical fuel filters, just strainers at the fuel pump.. If it were clogged you'd have bigger problems than a rough idle..

As for the fix for it, you probably would have to perform many checks such as spark plugs, intake filter check, MAF cleaning...etc

that would be the only way to get down to the source..

But there are many things lacking from your question suck as are there mods on the car? What mods? Is it tuned? By who? Was it running good before? What happened, when how?

Hopefully that helps...

 

IAC Valve going out maybe...?

 

boost leak???

 

adjust the BISS - see service manual for "how-to"

if you have evoscan to actuate the test its easy peasy......

 

Sorry i forget to spefic about the car...
I have an act 2600 clutch and prolite flywheel that was installed about 3 weeks ago because my clutch went.
Other than that the car is completely stock...i dont even have an after market intake
