Spi Putting Back Together
#1
Posted 04 January 2018 - 09:37 PM
I wonder if you could help. I took off the inlet manifold (94 Cooper spi) because the temperature pressure compensator was not working. I did not expect as many vacuum hoses and sensors. Anyway I managed to get it off and the tpc is knackered, I rebuilt and started to put back together and realised I should have taken photos, however after a few errors it is back together as it should be.... I think. Problem is it does not run right, it fires up, struggles, then dies with a kind of backfire.
Not sure what I have done wrong but I cannot work it out.
Any help much appreciated.

Just an update.
- I have checked all the vacuum hoses and connections, these all seem fine.
- I have the fuel lines correct: red fuelling and green (kinked pipe) return.
- All the wiring is now correct.
- The vacuum hoses to the breather/purge control are now in place
- The vacuum to the brake servo is in place.
- The TPC sensor went back in with the big circlip and was solid.
- Coolant hoses attached and system topped up.
- Accelerator cable back in place - can this disturb the throttle sensor?
It runs rough as if firing on 3 cylinders. It then backfires from within the manifold cuts out and you get a small amount of smoke. It is as if it is over-fueling. Thinkg was it was running fine before but I thought I would see what the problem was with the TPC!
Not sure what I have done and what I can do to fix it. I suppose I could do with hooking it up to diagnostics.... which I do not have!

There should be locating rings on the inlet ports to stop you doing that.

Just found 2 locating rings on the garage floor under the car!!!!
I'll get good at taking the inlet off and putting it back soon!
Thanks for your help.
