  • [Corsa B 1993-2000] Corsa 1.4 STINKS

    Sucks corsa b, has always been a bit hr and miss with emmisons, but recently it absolutely stinks!

    Idle is getting very bad, sometimes cutting out, and seems worse when engine is hot, but isn't perfect when cold either.


    Ideas?

      I did think between that and ICV. I think CTS is recent though

          If no EML is on and CTS is quite new like you mentioned and serviced recently then might need Opcom

            Told her to give it some just now, and Eml come on, so hopefully it will show up on opcom now.

              Opcom brought up TPS hose blocked.

              Looked at hose was bit fold back on itself. Idling nicely now, and no smell so far

                  If that hose was folder back on itself chances are it's collapsed internally. I'd try replacing it and see what happens.

                    We'll it was ever so slight, it's in that area between battery water bottle and all the other crap that comes with ecotech engines.

                    I was thinking Taurus that I could be the hose between the TB and Inlet (around 2inch diameter as a guess) can't be many more hoses around that area.?

                      That's an interesting screenshot.

                        Hmmm - there's a number of things that can cause the ECU to see an inlet manifold pressure that doesn't match the engine load. Start with the simpler ones, check the hose running to the MAP sensor, make sure that isn't blocked or leaking. The other thing that can happen is a dirty throttle body and sludge getting into the hoses attached to it. The 1.4 and the 1.6 are a pain in the bum for issues in that area due to lack of access.

                        But check the hose you moved, even moving it slightly may have opened it up, and then the vacuum created by driving has sucked it closed again. If they collapse internally there's no sigh from outside, you'd need to remove it and inspect.

                          Thanks for help, I remember visually checking map sensor hose, it looks nasty, and all the black on it was rubbed on my hands almost instantly.

                          How can I check if it's fractured internally? Just blow down it?

                            Removed map sensor hose, and map sensor nipple come off with it, so need a replacement now.
                            Hose was not fractured inside. It was strange how all the black on it was coming straight off though

                              If the MAP sensor nipple came off with it then it would have been leaking. That may well be your problem.
