After running countless injector cleaners (techron,seafoam, ect)i see that the chiltons manual for my truck calls for a fuel filter replacement every 15,000 miles. My truck starts hard some mornings after sitting, but is fine after initial start or even sometimes the first cold start. Could the fuel filter cause this after only 25,000 miles?

 

Could be the sticky/dirty IAC...

With that low of miles, I'd bet that your are still under warranty. Are you getting any codes?

 

no codes so far but it's going in @ 30,000 for trans flush ect.How do i clean the iac?
thanks
