E36 328
This has been copied across from another forum as i really need to get this sorted asap if the car is coming to fcs so sorry if it doesnt make sense! Background information, the car is a mk1 with a b18ft from a volvo 480 and when i first started it i did not have this problem, it has only come after fitting the downpipe. anyway, heres the original post:
Original post:
Fitted my downpipe today (thanks reevio ) and went to start it and as soon as i start the car it will slowly rev up to 3k and sit there. If i press the accellerator at all it will cut out straight away.
It wasnt doing this before I fitted the downpipe and that is the only thing i have changed since i started it last! I have had a look on the (very quiet) volvo forums and have found that it may be a bolt that i have missed thats function is to fill a hole which becomes an air leak but this was missing when i started it without the downpipe still and it didnt have the problem. Could it be the extra back pressure from the downpipe causing the engine to suck more air from this hole??? Just throwing ideas out there lol.
I am going to try putting some more fuel in it as it is VERY low and putting a bolt in the hole tomorrow but in the mean time does anyone else have any ideas? We have had some rain over the last few days, could this be anything to do with it? Water getting in the sensors (wouldnt be the ecus, they havent been outside at all)
Here is a video, note the rising revs until you see the accelerator cable move and then it cuts out immediately
edit: Does the fact is cuts out when the accelerator is pressed a sign of an air leak cos thats what my thoughts were regarding the rising revs
edit: Yeah it does have a tps and it's plugged in. Seriously literally nothing has changed since I started it for the first time and it ran fine then! Could it have got wet? It's right in te middle of the engine bay so doubt it?
Just put the bolt in I was talking about and connected te exhaust and lambda and it's still doing it. Doesn't just idle up to 3k either, gets to 3k, hovers, revs dip then it cuts out.
edit: Would it have anything at all to do with the way the car regulates turbopressure. ATM the turbo is not connected to the throttle body because I don't have enough piping and really don't like buying things for it without knowing for sure whether it's going to run ok or not.
The three pipes connected to the turbo go to a little box that has a plug in it. Because there is nothing for the turbo to push against would it make it go funny and keep revving? Until it thinks f**k it and cuts out lol.
Pleeease help csers!
