Hi there,

best first check the engine compressions, no use doing a tune if the comps are low. Also get a scan done to check for any unresolved fault codes, start here.

Hi there,

This is a simple job but you do need a comp tester, do you have one? Let me know and I will talk you through the process.

Hi there,

Warm up the engine, remove spark plugs, number leads so as not to mix them up, remove coil lead from distributor and earth, fit comp tester into spark plug hole (they normally screw in) with full throttle crank engine over 2-3 revolutions, note down comp with Cyl no, re set comp gauge to zero remove and fit into next cyl, do same as first. Do all 4 and report comps here, you can do this twice with a little oil in the cyl this is a wet test do this after the dry test and compare wet & dry readings of each cylinder, this is what I need to know.
