Vehicle has a very loud knocking noise only under acceleration (heavy acceleration). It sounds like detonation (the "marbles in cylinder" sound).This only happened after I changed the plugs and 2 of the ignition coils. I initially received a Restricted Power light and my check engine light came on. So while I was changing the coil pack I figured I would change the plugs as well. I also need to know the cylinder firing order for the car. right now the car isnt performing at 100% power when hard a

There is an engine knock or loud ticking all the time. It seems to be coming from the right cylinder bank area. When I disconnect the wires to the different coils it changes. there could be more than one source of the knock/tick. Sometimes it sounds like a lifter tick. Other times it almost sounds like a wrist pin knock. Are there any common problems with this engine? I am going to tear into it tomorrow. I am a primarily domestic vehicle tech with 20+ years of experiance.

You are right, most likely a lifter !!Crank shaft bearing (rod) may be, or a broken piston ring will do it also, while you have it apart check these! ... 1999 Acura SLX

I have a 2 door 2003 pontiac Sunfire that sounds like a airplane or lawn mower engine when I accelerate and while driving (but gets worse when I accelerate). The sound lessens when I come to a stop.

There is a clicking sound that emanates from the driver side of my '05 Pontiac G6. It sounds similar to the sound an ignitor on a gas grill makes, only constantly. The noise goes away immediately when I turn the heater & a/c off (to 0), and conversely starts back up when the heater is switched back on. There are very few moments when the noise goes away on its on, but they are very short lived and far between.
