v6shep Posted June 3, 2015 Share Posted June 3, 2015 Hi guys, had oil change at weekend, not driven car as it's got no back brakes at the moment. Started it today and on startup, it's throwing out some really black smoke. Any ideas? Also over the last week or two, when the car is warming up, instead of dropping revs once warmed, it's going up to 2k revs Many thanks Shaun Quote Link to comment Share on other sites More sharing options...
Mk4Gaz Posted June 3, 2015 Share Posted June 3, 2015 Black smoke could indicate very rich. Have you changed anything else, or checked that everything is plugged in, and all vac hoses are good? Quote Link to comment Share on other sites More sharing options...
v6shep Posted June 3, 2015 Author Share Posted June 3, 2015 I've not touched a thing, I'm not mechanically minded in any way so let the garage do it Quote Link to comment Share on other sites More sharing options...
Tyson Posted June 3, 2015 Share Posted June 3, 2015 As above black smoke is unburnt fuel, check there are no disconnected wires or pipes in the engine bay. Have you left it running and see if it finds a proper idle ? Battery may have been disconnected and it's relearning. Quote Link to comment Share on other sites More sharing options...
v6shep Posted June 4, 2015 Author Share Posted June 4, 2015 I'll have to look over the weekend. It's been doing it on and off for a little while. But doesn't seem to want to go down in idle just goes up. Quote Link to comment Share on other sites More sharing options...
v6shep Posted June 6, 2015 Author Share Posted June 6, 2015 Ello again guys. Just wondering, does this look wrong? And do these look correct? Quote Link to comment Share on other sites More sharing options...

v6shep Posted June 7, 2015 Author Share Posted June 7, 2015 Brakes sorted. Pistons where all the way out. Nothing a G clamp and a piece of wood couldn't fix. Not bad for my first brake replacement. Any ideas why the car is running so rich? Can smell it a mile off Quote Link to comment Share on other sites More sharing options...
baldy Posted June 7, 2015 Share Posted June 7, 2015 Maybe a vac pipe knocked off when getting the oil filter off Quote Link to comment Share on other sites More sharing options...
v6shep Posted June 7, 2015 Author Share Posted June 7, 2015 Cheers baldy, I'm guessing there wouldn't be any under the car near where filter is? It's starting to level out now on idle instead of going up to 2k idle. But on startup it's a bit spluttery, another thing it never did before the garage did my oil change Quote Link to comment Share on other sites More sharing options...
ATB Posted June 7, 2015 Share Posted June 7, 2015 If the battery was disconnected the car has to learn everything again which only a quick drive can fix. Quote Link to comment Share on other sites More sharing options...
v6shep Posted June 7, 2015 Author Share Posted June 7, 2015 Well my alarm did kill my battery not so long back, had to take it out and charge it. But does that cause the rich stink and black smoke? I've looked at vac pipes and all looks good, none loose, no splits etc Quote Link to comment Share on other sites More sharing options...
v6shep Posted June 9, 2015 Author Share Posted June 9, 2015 Jesus, just started with a new problem... Anybody know why all the way to work my car was at nearly 4k revs? Quote Link to comment Share on other sites More sharing options...
Dnk Posted June 9, 2015 Share Posted June 9, 2015 Think your calipers are long overdue some tlc going by that photo and i don't mean painting them Quote Link to comment Share on other sites More sharing options...
mellonman Posted June 9, 2015 Share Posted June 9, 2015 I would start a new thread for that one , not ever heard of that or a little more of an explaination would be better to help you , 4k revs to get the car moving 4k revs on its own, it wouldnt pass 4k revs , when stopping its at 4 k revs when pulling away its at 4k revs , could you stop it in anyway ? if you have a auto bpu tt that would be one hell of a fast drive in and doing burn outs everytime you would have to stop. what spec is your car ?

v6shep Posted June 9, 2015 Author Share Posted June 9, 2015 Think your calipers are long overdue some tlc going by that photo and i don't mean painting them Funny you say that, got a rear caliper at THE BRAKE CALIPER SPECIALISTS, only been there 14 months, the last time I spoke to them last July, I was told I should contact them ask where they have put it as it never arrived.... I work for the courier, and have proof it made it there safely Quote Link to comment Share on other sites More sharing options...
