Hi there !
2L Duratec HE in a Focus 2009, I have 3 brand new engine mounts that I thought would solve the seat vibration issue (dash appears OK, just the seat/feet/outside of the car) but it didn't do anything to help it.
all 3 mounts are OEM Ford, paid good money for them, and zero contribution ! Not totally upset though, they needed replacing anyway - But I don't like to gamble so here I am asking you.....
The character of the vibration is like, quiet, quiet, quiet, mega vibe, quiet, quiet... mega vibe... about 3-4 second apart
Test so far:
-4 new spark plugs, cleaned throttle on both sides...
-Idle is steady, no corelation to vibration.
-Timing advance doesn't seem to produce negative values.
-Throttle Position nicely sweeps between 0.7v to 4.5V.
-Spark gap measured at 1.3mm
- MAP appears fine
-WOT on a hill shows no hesitation to speak of
- Removed Manifold butterfly runner vaccume, same.
- no EGR Faults on OBD.
- Ignition Voltage 12.3V
- Reset Keep alive Memory on ECU/TCM no use.
- Tried two different brand of lower torque mount, OEM and Febi Bilstein - Same
- New Air filter
- Fresh oil/Filter (castrol)
- Zero OBD Faults on all modules. ECU/TCM/HEC and the rest of the ford modules all clear of any codes.
Findings, not sure if it matters or not.
1. Opening the oil cap with car running, I can leave the cap on the hole when loose, and it will rattle in place. So there is some pressure going out but it won't knock the cap in the air. Normal ?
2. The tailpipe removes gasses in very similar manner to the "pumps" I feel in the seat. bababum, papapapabum, papabum, papapap pabum. Not a steady stream of air. Normal ?
3. I blocked the tailpipe to see if theres a gas leak, but all that happens when you block it is silence...
4. Possible relation - When I kick-down the 4 speed automatic and let go at 6k rpm, the car won't upshift and relax. It will often stay in that gear and slowly get down the revs until it shifts up/down. I know for a fact this isn't normal... Shifts are fine, proof is, manual mode is flawless. So must be non-tranny related.
Any ideas ?
