Hi guys.
This is my first post here, though I've been browsing here for a while when troubleshooting things. Sorry for my english, I'm a finnish dude so its defo not fluent!
So, I'm having some nasty problems with '09 tourer 2.2 iDtec. The car has 233 000km on it's clock.
Symptoms:
- The fault is continuos and has been present for about a week now.
- When idling, the engine "misfires" randomly at 1-20 sec intervals.
- When driving, the car stumbles at same intervals.
- When reaching normal coolant temperature, car tends to cut out. There has been couple of occasions, when I had to wait for approx 30min after the cutout to get the car started.
- Otherwise the engine starts easily and there's no excess smoke to be seen.
- NO check engine etc. lights flashing.
Notes:
- No fuel leaks.
- NO DTC:s to be found. I've read the log with Auto-Com & launch pro -testers. (No access to HDS yet).
- The car is re-mapped with dpf & egr elimination.
- The fuel filter has been changed ~2000km ago. Oem part.
- We were able to do a rail pressure test with launch pro. Result 1800bar.
- When idling, the rail pressure is around 260-280bar. The MAF-voltage is ~1,8V.
- Dunno the right term in english, but theres a slight difference in the injectors "correction amount" Cyl. 2 is -1,7 while the other ones are at +0,6.
- Most interesting thing is, that the crankshaft pulse sensor gives the values of either "63220" or "0". Revving the engine doesn't affect the values. Still, the RPM-signal is correct at the tester.
If theres any hints or ideas where to begin, I'd be glad to hear those! Taking the car to the dealer service is the last call, as its gonna cost some serious money..
