E36 M52B28 Misfires once warmed up with decreasing rev range
Bushmechanic replied to Bushmechanic's topic in Maintenance
UPDATE: Issue fixed. New Cam and Crank sensors have been fitted along with temp sensor. no more codes and car runs perfect. outgoing cam and crank sensors have been tested as ok. pretty baffling scenario here. but I'm just glad its all over! thank you everyone that tried to help. Much appreciated. I am now in the process of setting up a cold air intake and installing new roof canvas. that's going to be fun! -

Just scanned it on my machine. Gave crankshaft sensor fault 83. I cleared the code and started car again. No fault codes present. I will test drive tomorrow and recheck. Can by the by, crankshaft sensor is new. -

They gave me the car back telling me the issue is resolved. Its not. But they wouldn't release the car until we paid them. So I've really paid for something that's not fixed and now I have another issue as a result. I'll take it back and see what they say. I understand from checks everything is OK including compression and fuel pump. All hoses have been checked and I understand a smoke test was done to see if there is a vacuum leqk. None found. My scanner kept showing camshaft sensor after I replaced it. So I replaced it again. No change. They have gone and done the same. The only difference is that they pulled out the DME and checked it. Saying it was damp they replaced with a known good item but the problem remained the same. So wasn't the DME. -

They charged me a premium and I need to get my money's worth! -

It happened only when the car was warmed up. What you described would happen at anytime yes? -

Thanks heaps zero this is awesome. I will check this out. I'm fairy on to it mechanically so shouldn't be an issue to tackle this. The car spent 2 and a half weeks at Ron Wood auto getting scanned etc. They tried all sorts of fixes and eventually replaced an already replaced camshaft sensor. Although the misfires have decreased its still there andbi van replicate it. The car is now missing at low revs and cuts out. Also has very late starts. So I consider this a step backwards. All the bits i replaced improved the car but did not fix or worsen the misfire issue. I will definitely check out your suggestion on the resistor. The problem originally came on very suddenly. My guess is that something let go and I instantly had a problem. -

This is very helpful! I will eventually need to take it to Glenn. At this stage because I have spent the cash with Ron Wood I'll have to take the car back there. Don't get me wrong though, would love to take it to Glenn! -

Have you got more info on these resistors? I feel the misfire issue has not been resolved and I have spent money replacing a good camshaft sensor that didn't need doing. -

I thought Ron Wood was a reputable place. Now its not? -

Hi all. An update for you. The car has spent 2.5 weeks at Ron Woods. They eventually swapped out the DME as mine was damp with a known good item. The problem remained. My DME was dried and put back. The camshaft sensor was finally replaced. However the car still misfires but now additional issues are missing on low revs, not as responsive as it was before and cuts out after its been run for a bit. Misfires are not consistent. Sometimes it will and other times is won't. There were no vacuum leaks and DME seems to be fine. So what now? 2 and a half weeks, 800 bucks and a third camshaft sensor later. -

I cant really get the car past new lynn. I would love to get it checked properly but do have work commitments. Unless someone knows of a good place I can go to on a Saturday afternoon thats close to new lynn. Glen I see you are busy but would appreciate you taking a look if possible. If not I have heard of jaybee electrical which isn't far from my house and the car can make it there. Anyone used them? just a side note. The car has been kept in a garage ever since we have owned it. It has kot seen any heavy rain etc aside from the last wash i gave it. Surely thats not enough to allow water into such an important item? -

Car has been scanned numerous times and varius things disconnected and checked for faults. The problem remains. Car misfires when temp guage hits half way. But the problem improves if you let the car cool down. This has to be temp related yes? Fault codes indicate camshaft. After misfire you see crank shaft sensor join the faults list. But can be cleared. Camshaft sensor fault can only be cleared with engine not running. Soon as you start the car the fault comes back. Has to be something simple surely -

Ok some one mentioned temperature sensor. I assume this is the engine temperature sensor. I tried disconnecting it and running the car. The only diff was my temp guage didnt work. The car still misfired. I cant understand what the issue is. I have screen shots of all the readings from the scan but dont know how to post here. The issue arises once the car is warmed up nicely. Temp guage half way. When the car cools down again the issue retreats. I love this car. Some one please help -

Hi all. I have haf the car checked on a scanner. Gave crank and camshaft sensors. The faults were erased but it throws camshaft sensor again and again. The cam and crank sensors are new so I was very surprised it guves the error. I went ahead and replaced the camshaft sensor and rescanned erased and took for a run. Came back with exact same issue. Misfires exactly the same. Scanner shows cam and crank sensors. Erased then come up with cam sensor only. Very confused!!!! now I am doubting the new camsensor was the issue at all. Its got a new set of coils and plugs. New sensors and new vcg. What now? Am I missing a vac leak somewhere? Only does it when temp guage reaches half way. please help!! -

Wouldn't that throw a check light? -

yup agreed. I have ordered a new VCG as it needs doing anyway. but will wait for the diag results before going further -

Hi guys yes revving to redline probably isn't helping it, but I don't do it at other times. Just now that I have this issue. Yes OEM sensors and coils. I had a chat with a parts guy and he asked me about oil leaks around the rocker gasket, suggesting that a significant enough leak may be causing a vacuum leak? any thoughts while I wait for results from the workshop? -

Not scanned yet. Will be done this weekend. What are the reasons it may behave this way suddenly. Especially given I have changed components? -
My E36 (NZ New 124k on the clock) is a bit sick. It has developed a misfire once warmed up (heat gauge about half way). when you first start it up she runs great and can rev her to the red line no problem. Then after a bit of driving misfires at about 5500 rpm. Over time it does it at 4500 rpm then 3500 rpm etc etc until its doing it at 2000. You cant drive it after that. it idles fine and starts up no problem. Yet once warm it clearly starves when loaded. The engine does not cut out at all though. Back ground When I bought the car it had an intermittent missing and cutting out issue. My mechanic suggested I replace the cam and crank sensors as the code it was giving indicated one or both were faulty. I did that and the car ran fine for about a month. Suddenly out of nowhere comes this misfiring issue. I figured the plugs a probably toasted and all were so I replaced those with NGKs recommended items. Mechanic suggested I replace all coils so I did that too and the air filter. The car has slightly more power but the misfiring is identical to before the new coils and plugs. I have checked for vacuum leaks and cant see anything worn. All clamps are tight. There is a slight oil leak from the rocker gasket, but that been there since I got the car. So to sum: New crank and cam sensors New coils x 6 New plugs x 6 New airfilter Can someone help please? could I have a defective cam shaft or crank sensor? Or do I have a vacuum leak and I need to look harder? Thanks in advance
