Update on misfire Thanks to Peter D for pointing out the engine type, should have been D4F B 712 16v 1.2 (also for the phone call this morning) Ran from cold with vac gauge connected and ran at around 15/16 Hg When warm it idled at 18 Hg (needle steady, not bouncing around), but held at 1500rpm it dropped to 14 Hg at 3000 came back up to 17 Hg, a quick blip on the throttle and it dropped below 10 Hg then came back up. Not over happy as i thought it would be around 20 Hg at idle. Would the misfire affect the Hg? Carried out a cylinder leakage test, fluid stayed blue after 5 minutes Ran a flush and fuel cleaner for 20+ minutes Carried out a compression test (had to borrow one as this has the tiny plugs down a long tube, need to get a new adapter for my snappy one). Compressions all good rising to 175 evenly over 3/4 seconds (all 4) Next i checked the injector ramping on 1 and 4 as these are only accessible, the voltage check was ok but the current ramp on No4 kept dropping out intermittently (flattling every second or so), could not get the clamp on the middle two I have told the customer its probably an injector fault, but cannot confirm all 4 because of access, he wants me to change all 4. Having got them all out the resistance is 15 oms on all 4 I also explained that is also a possibly that it may be a bad connection/wiring fault or even ECU, but he want's injectors changed, then go from there Many thanks for all the suggestions, will keep you posted (new Pico's great )
