friend of mine needs help

wp23n · 11-01-2009, 05:30 PM

he replaced the Master Cylinder, bled the brakes and after that, A problem started.

This is what he says happens: When engine starts there is a slight hesitation, and some mis-firing. Then as engine warms, it really starts to buck and kick.

Then he did cap, rotor, wires, plugs and fuel filter hoping that would remedy this new problem. this didnt help

Today he checked timing belt alignment on the camshafts.

other than a new cap and rotor The distributor and timing hasn't been touched.

anyone have any ideas?

Did he check for vacuum leaks? Maybe left the brake booster hose disconnected? Make sure he installed the new ignition wires in the correct firing order.

It could be many things... could be because of the fuel, the lamda sensors, hal's sensor... and those things above... he should check everything mentioned

Just for clarification, did he ensure that the crankshaft was at TDC when he checked the timing belt alignment on the camshafts?

Also, have the diagnostic codes been read? (Page FI-21 in the BGB)

+1 re checking the spark plug wire installation for the correct firing order

i believe he double checked the firing order but will have him check
also there is no check engine light so would the car still store codes?
