Hi guys, need to pick your brains here, have had an intermittent stutter at low revs say under 1400rpm on and off for a while now and the occasional cut out at junctions, scanned it and there are no faults, I suspected a faulty loom and finally got around to changing it today as I had a couple spare (thanks Gizmo), a big thanks whoever came up with the hairdryer trick to soften the new one up, the old one fell to bits
Anyway the problem persists, have changed vac hoses recently, egr is disabled, recently serviced with filter change, check cam and all is good, doesn't smoke, starts on the button and goes like stink but it misses at low revs??
Checked MAF, checked MAP sensor still didn't affect it, pulled alternator plug and cleaned it.
I had a new battery last year and might check this, and the voltage etc.
I thought I could hear a slight hiss coming from below the plastic intercooler hose where there is a valve with 3 vac hoses on it, one of them is the EGR one which is blocked, the 3 pipes that clip on the back of the inter cooler hose, what is this valve and could a slight leak there cause an intermittent stutter?
The hiss could just be the air running through the intercooler hose I am not sure, I am at a loss now?
Any more tests/logs can be done with VCDS?
Cheers
