BMW E53 E39 E38 4.4l M62tu ICV Idle Control Valve rough Idle Loss Of Power 

The video very helpful I was about to ask about the secondary air pump valve and mentioned that in the moment like you feel me ! I did the timing chain guide two months ago and the mechanic broke the inlet hose for the secondary air pump but I didn’t see that only afew days ago when I tried to change the inner wheels cover

Hello Nathan and thank you so much for the clear vids and instructions..... My question today is... Can a coil pack throw a P 1189 P 1188 ? Or where should I look?

Will rainwater down in the coil housing cause rough idling?

Hi , I have replaced the cover and diaphragm but still lots of noise coming out of the oil dip stick , oil filler cap hissing and difficult to remove , burns oil as well . Engine runs fine , no misfire anymore but still has vacuum leak and oil burning . Is this can be bad oil separate valve which behind the timing chain ? Or clogged vent tube under the intake manifold? I love your videos , they help alot . Thanks .

If a 540i makes noise on startup for 3 seconds even with new tensioner, what do you think might be wrong?

I see you don't seem to reply to comments but I figured I'd ask anyways... there's an electronic part that's connected to the vacuum like on the driver side of the ccv. The electric thing is near the front of the car though. In my 2001 e38, it sits by the oil filter and whatnot. What is that for and how can you tell when it's bad? I replaced my whole ccv and it has that annoying whistle along with an SEL for bank 1 and 2 too lean. I've replaced the MAF sensor, all the ignition coils, the fuel filter, cleaned the fuel tank and checked the fuel pressure. I've replaced all of the o2 sensors and all of the intake gaskets too. Oh, it also has a new battery... I don't think the brake booster is bad, but I'm not sure because I have a "brake" light on my dash and I'm not sure why. The pads are good, but maybe the sensors are bad? There are pixels out, so I can't make out exactly what it says, but it says something about check brake... The previous owner was an idiot, I'm trying to save it because it has low miles and it's pretty clean all things considered.

Hey, i have one situation, please help me if you know what it is. Sometimes by cold engine my 4,6 Rews on and than goes immediately off , after couple minutes goes normally on and stays. He has a problem with idle when you revs engine it kind take heavy engine idle back. It sinks to 450-500 rpm and than comes back to 700 Can it be vacuum leak?

Please could a bad cam sensor on bank 1 also cause this issue?

hey all i ,im insan,here iwant to ask about the problem of 740il car in 1993. start my crane trouble cover gasket broke so oil engin go to plug coil without real time i continue to change coil and plug. so here it is all done I try to start my engine 6000km terkanan. please explain what the problem is, either Maf or IdIl, or as it is

Nice informative video. Thanks

Hey Nathan i have an issue with my 01 x5 4.4i. It had long cranks with multiple misfires codes. Now is also stalling. I put new coil packs new spark plugs, fuel filter, fuel pump, new vacuum hoses, cleaned the throttle body, cleaned the mass air flow sensor. I have no other codes just multiple misfires

hey Nathan great video as all ways is it possible to change the timing chain guides without moving the chain and the fancy tools for locking the camshaft on a 740 il . thanks

Nathan will u please email me I have a question about a broken pin in mechronics unit thanks

MAF SENSOR!!!!
