mark. When I step on gas it stops for a while. It may come on again if car is going slow but if it at a speed where air is coming in then it doesnt come on. Any one know what this is? The car is Jetta '89. Please help if you can...thx
Your most likely running 10-30 or 10-40 motor oil. For that vintage VW's thicker oil was specified for above 50 f as I remember. 20-30 would be more suited for warm weather in that vintage. But the reason is the oil pumps were weak. You can put a pump off a mark 3 vw engine on and you'll then be able to run the thinner oil. I once bought a Brazilian made, VW branded pump intended for the 93 and up 2.0L engine for $80 on line and cured the problem on a 92 jetta. It also ran better because the lifters had enough oil pressure to them.
