well while taking apart my car i found that there is no flame trap or vac. line runing to the manifold. could this be the cause of my rough idle?

 

I would say It could have a little something to do with it.I would not say it would be the main cause.

 

got it all back together, new plugs also. now it idles better but seems to idle rougher in gear. i adjusted the idle speed in nuteral. no more black smoke, and has a lot more power although hesitates when taking off from a stop.

 

Some of them are like that always.

Bye the way what are we working with here?

 

83 240dl b23. moved it last night and it acted like the ilde was to low will adjust it again when it warms up alittle.

 

Looks like you almost have it.They always kind of have a little hesitation.I had a 82 240 with the CI injection and that thing was alomst as slow as a turtle.But it was a 5-speed and you could work with it a little.

 

its getting better. dug a little deeper today, found that the knock sensor was disconnected. put it back on, cleaned the idle air control valve the best i could, couldnt get that guy out. adjusted the idle in drive. running better but still have to babysit it while it warms up. ill keep tinkering, any suggestion would be great. i dont think the previous owner did much with it. thanks tech
