Carb cleaner works great.I've heard of that, yes, also water too or water and soap. Tried the water in a spray bottle and so far have not found any leaks when I last did it a week or so ago.
Just noticed this.P0102, MAF low
P0103 MAF voltage circuit too high
P0230 Camshaft sensor (mine has scratches on the surface, bad?)
P0300 (obviously as it's the general random misfire)
P0304 Cylinder 4 misfire
P0401 EGR flow insufficient
In fairness, I did go with the cheapest shipping option and RockAuto is a very well organized website.I've been waiting three weeks now for my damn axle nuts from RockAuto.
