My 2003 punto mk2 2B 1.2 8v 60Bhp has developed a fault,at low speeds under 30mph it hunts aggressively, at 40+ its fine.
I was told the fault could be the egr valve, but I'm unable to locate it, so far I've changed timing belt, plugs leads, coil packs throttle sensor, map and or crank sensor,pre cat o2 and post cat 02 sensor, cleaned the throttle body, and developed a misfire sound as though firing on 3 plugs, I've added injector cleaner, and the result is low power until it warms up,
My engine has no leaks and only 60k on the clock, now it's show an engine management light, any help would be appreciated
Thank you in anticipation
