I had a hot start issue that turned out to be the Warm Up Regulater (WUR). I discussed it with Larry Fletcher and he provided a rebuilt WUR that...
And, I will check the nuts - if I can reach them, that is. QUOTE=don_xvi;141910283]Don't you hate these? Easy thing to try is seeing if any of...
I'm actually relieved that apparently there isn't some secret oil supply hose back there that is impossible to get to. Can the cam cover gasket...
'86 328 - Noticed a burning oil smell and found that oil is dripping onto the top of the exhaust pipe below where the dipstick disappears at the...
I don't have a pressure tester, so had to use a process of elimination. If your car idles smoothly when cold, but won't idle smoothly when warm,...
WUR - Warm Up Regulator
WUR - as best I can represent it, is a device that controls the idle fuel pressure based on the time it takes for the 12V signal to the...
My 86 328 was unable to hold idle when warm. Larry Fletcher rebuilt the WUR, and the issue is completely resolved. One more thanks to him...
Excellent. Thanks, Steve.
Thanks. I thought so. Also, I just found an issue that is likely causing a cold start rough run problem. The female plug that goes onto the WUR...
Is the WUR supposed to get 12V as soon as the engine is started or after a heat sensor says the engine is warming?
Sigma, I replied recently with a request for one black and one red on the previous thread. Is that adequate or should I (we) re-post the request...
They look great. I'll take one black and one red, please. Thanks.
It is a US version. Up until now, I have not needed fuel pressure testing equipment. Sounds like I will need that plus the specs manual you...
'86 328 - I have been searching old threads (unsuccessfully) to find out what electrical current should go to the WUR at start up and for the...
Only when slammed enough to engage the catches. If i lower it gently, no issue.
Sorry. I should have been more specific. It stumbles and then recovers in 10-15 sec.
When I close the engine cover with the engine running, it stumbles pretty hard. So, I used a rubber mallet to gently bump every component I can...
Rob, typically, where is the fuel pressure accumulator? I have a hot start issue and a possibility is that it bleeds off causing a possible vapor...
Just got in there and it reads F105C040, so its a US Spec engine.
