2006 VW GTI Misfire
I Have a 2006 VW GTI 2.0 turbo. cyl misfire 1,2. has no vacuum leaks replaced intake manifold gaskets, new coil packs, did compression check on each cyl tested ok. At idle it is a little rough but when you are driving it very smoothe. Has a lot of power. also had a random misfire PO300.

could use some help

Have you changed the spark plugs also? also can you check your last gas receipt? maybe you have diesel in petrol? have you checked the injectors? also the fuel pump pressure... i think you must have over 3 bar?

Check/clean/replace: coolant sensor, MAF, MAP, Valve carbon build-up, cam follower/cam fuel pump if installed
