Post by scorpioaaron on Aug 26^th, 2017, 1:38pm

MAF Sensor. Take off and clean with a good carb-cleaner (smells like thinners) Don't be tempted to fiddle about with anything sharp to remove bits inside. First port of call. After that it's EGR valve, and the pipes to it. Then the sensor for the temperature in the inlet manifold, then throttle position sensor. How's the fuel-loom? If the wires are brittle.................! Try those, and get back to us.
