ThePokerNut Posted January 11, 2011 Share Posted January 11, 2011 Wayhoo ! I've just MOTed the Cav. But while driving back from the garage its started to run really rough. I pulled over, poped the bonnet and had a quick look. Nothing noticeable so jumped back in and put it into drive and stalled ? ? ? Turned the key, fired up first time no problems, gave it a couple of "GOOD" revs to clear it and sounded fine. Engenged drive and stalled again ! Managed to get it moving but now stalling every time i stop and try to hold it in gear. Drove fine to the garage 8miles or so.Any ideas as where to start looking?

Chris I had that problem on a transit van, the early ones, in the 80s, and the cause of it stalling when put into drive, 1st or 2nd, was a faulty servo that was causing the brakes not releasing, thus causing the engine to stall when you engaged drive. I'm not saying that is the fault, but worth a decko! what's the condition of the manifold/servo vac pipe, is it in good nick? Don' be offended when I say " have you checked automatic fluid level too!

gary6303 Posted January 11, 2011 Share Posted January 11, 2011 think there is a vacuum pipe that goes to the gearbox it could have split, perished, fell off. Quote Link to comment Share on other sites More sharing options...

Checked the servo pipe, no problems there. Oil level spot on in gearbox, but this was my first thought! lol I haven't checked the vacuum pipe on the gearbox yet Gary, but will crawl under and check that out.

cam.in.head Posted January 12, 2011 Share Posted January 12, 2011 check the small joining hose where that vacuum pipe from the gearbox joins to the inlet manifold. Quote Link to comment Share on other sites More sharing options...
maher the hermit Posted January 12, 2011 Share Posted January 12, 2011 I think on the carb linkage there is a vacuum control (anti-stall valve) that pushes the linkage to up the revs slightly when putting the gearbox into drive, check this is working and the vac hose isnt split between the box and this unit Mick Quote Link to comment Share on other sites More sharing options...
ThePokerNut Posted January 17, 2011 Author Share Posted January 17, 2011 Thanks for all the advice, checked all the pipe's and vacuum controls and still stalling. I'm at my ends wit with this. Gonna have to get my local garage to look at it, not what i really need just after xmas. Quote Link to comment Share on other sites More sharing options...

Not likely as autos don't have a clutch it shouldn't stall regardless. What spec is the car? Carb, injection? I'm not going to assume as so many are running injection or different combos.

ThePokerNut Posted January 17, 2011 Author Share Posted January 17, 2011 It's running a solex carb, been fitted for a while now. Came off an Auto so shouldn't think much of a problem? Last throw of the dice though, i'll flush the old oil out of the box and change it. If that doesn't work i'll throw the whole tool box at it.

cam.in.head Posted January 17, 2011 Share Posted January 17, 2011 my guess would `be...firstly............to make sure the engine itself is all ok.. with regard to all basic tuning issues etc so that the engine is running perfectly normal & at the correct idling speed with no rough running issues or faults. you mentioned about the car needing a rev to clear it so it suggests a fault somewhere. if the gearbox is working correctly then putting it into drive should only load it slightly. into creep mode. if it is stalling then its either a fault with the torque converter itself thou i doubt it. or maybee even a wire moving on a bad connection when the engine rocks as its put into gear. i had the same problem on my carlton & it turned out to be one of the wires on the starter motor terminal becoming loose in the lug. this` was on an injection car & it was the injection power feed cable. if yours is a non injection it could be the 6mm vehicle supply wire.(red) Quote Link to comment Share on other sites More sharing options...
mantapaperman Posted January 18, 2011 Share Posted January 18, 2011 hi chris. chances are if youve had it in for test and it ran fine before, the tester has adjusted the co content to bring it within limits? trouble is hes probly gave it a quick twist in the mixture screw and got a pass figure..but tuning a car can take more than that! now youve give it a run it may have settled too lean or rich and the idle speed may now be lower? i would have the co and idle checked by the garage that tested it..hope this helps..steve Quote Link to comment Share on other sites More sharing options...
