Ever do a 60k tuneup this decade.
if this is knocking combustion detonation, the engine will self destruct soon. ping or knock is cause by lean mixtures and very hot combustion, all very bad, do not go up hills that makes this worse.
i say get a shop to check it out. before it gets too costly to fix.
easy on any 91 car.

Hi my 1986 golf MK1 makes a knocking noise in the front which sounds like its on the body while driving, please help.


Those bushes would have to be shredded or missing for it to make a knocking sound. And should be a visible problem, I would think.

While idling, the engine sputters. check engine light on, reading misfire in cylinder four. Have replaced both coils, all wires, and all plugs. Still no help. I've come to a dead end. Anybody with ideas?.


Hi, this may be a dirty injector. Try putting some injector cleaner in the gas tank to see if that will clear it up. If not, you may need to pull up the fuel rail and check the injector flow pattern.

We recently had the timing chain jump on an Xtype Jaguar 2.0 diesel. We changed the timing chain and tensioner and fitted reconditioned delphi injectors, the car now has a very loud knocking sound coming...


make sure you have proper sealing washers under injectors,and you have only one washer in place ,ihave seen it happen before 2 washers will cause a loud knock if not that get injectors calibrated good luck

Not a good thing. More than likely it's the rod or main bearings.

Check your rotor arm, distributor cap, HT leads and coil. The fault could lie with any one of the above.
