Dont know if this has already been discussed, but i think it deserves attention. Thought I would change out my sparks and coils on my new baby. F10 550i. N63. Seemed easy enough, studied the engine and although not many diy aids, found some goodies online. Changed coils and plugs before on...

Hey Guys, This forum has been tons of help, so I thought I'd try again. I have a 2003 BMW 745i. Originally part of the ecu harness was disassembled. I used a wiring diagram from an N62 LHD USA, hopefully the right one, to reassemble it and got it cranking. Then I found out it wasn't getting...

Hi! Trying here on a bigger forum. Just swapped out my engine in my 318. Swapped to a M52B25 engine. I changed the ECU and cabels so it's matches the engine. The immobilizer in the ECU is removed so that wouldn't be any problem. But i dont get fuel or spark! Checked the cables and i have...

HELP! E36 won't start, with fuel and spark! My e36 97 328i (vert) will not start for the life of it! I've done a ton of diagnostics to no avail. I apologise in advance for the long post, I wanted to be extremely thorough. Here's what happened and the list of my diagnostics. I know the car...

Good or bad Give or take I replaced them anyway, some say 40k interval but I think that is way too long esp on a 12 year old car. I drive her hard maybe once or twice a month. Meaning: doing over 120mph for a couple minutes. Didn't having any issues I just felt like changing them since it's...

1994 bmw 318ic m42 engine 215k miles no check engine light Start car and idles great for 30 seconds then starts surging from 1500 to 2000 rpm constantly. Parked, or in gear, it does the same thing. Replaced icv, plugs, tps, and cps. I've read forums for weeks and can't figure it out.

I have an '87 325is and have been trying to figure out this issue for some time now. First, I had a hard bogg occurring, that was fixed with a refurbished AFM. Second, I was getting a cutting out intermittent misfire. I replaced the spark wires and dist. cap and it seemed to temporarily fix the...

Hey guys, I had SES light on intermittently. So I got my codes read from Autozone and got code P0302, cylinder #2 misfire. There seem to be two main causes: Spark Plugs or Ignition Coils. Since, I'm coming upto a 100k on my BMW, I'm going to replace all the spark plugs and see if the problem...

I've always used NGK BKR6EQUP 3199 plugs on my e39 and never had a problem... I'm wondering would it be fine to use the same type plugs on my e60 ? according to realoem, there were ENDED and replaced with part # 12120037607 (BMW)

Long time Lurker, First time poster. Thanks to all the wonderful people and information on this and other BMW forums [but especially this one] I managed to troubleshoot and fix a problem on my wife***8217;s vehicle. She drives a 2011 328i. We***8217;re still covered under extended warranty but...

Long story long, chasing a misfire on cylinder 2 swapped injectors, replaced coil, ran compression test (all good) Checked for vacuum leaks, loose wires etc. Also rebooted computer. Just for the heck of it while doing my compression test I grounded a few plugs with coils out and watched spark...

Hey guys, new here cause I've been on almost every bmw forum looking for an answer and still haven't gotten it. So, i thought i bent a valve driving out of my neighborhood a few weeks ago, i drove right back home and parked it. Started dismantling the head when i thought to myself that the noise...

Ok so to start out, I bought a 1995 325is rolling shell manual and put in a getrag and m50 in it. Should be plug and play, or so I though. So once it was all installed, the car started after a bit of cranking but it did start.But now it wont start unless we push start it in which the car...

I just got my 2001 530i back from the dealer and it looks like I need all new coils, spark plugs, thermostat, oil pan gasket and a vanos high pressure line. I've looked around for all these parts and it comes out to about $350 - $450 (dealership wanted $2,000). However, I came across a few parts...

Hi there guys. Now my more unusual swap (m50 in a volvo 245) has taken a turn. It has been up and running good for 3 months now but last week when i drove it a night it suddenly just cut out with no warning at all. Best described is that the engine died like when you turn your key off. Well...

I have a 94 530i. Mostly do highway travels, never in stop and go unless there is an accident on the highway but still yet. The one day I do go through stop and go traffic, I start having stalling issues. The car acts like the TPS has a dead spot, tries to stall out, bumps itself back to life...

So as you probably already know that this car has a 3.0L V8. After two days of owning the vehicle, the engine started to have zero performance and idle rough. Idle rough in the sense that the entire car is shaking. So I figured it might be spark plugs. When I went to replace the spark plugs, I...
