nusias9 -> RE: engine hesitation at take off (9/9/2007 8:12:38 PM)

Hi All, I have a 2001 Santa Fe with the exact same issues.
Cold start stutter/hesitation that resolves itself after a few minutes or forcing it to take off. Rarely there is a stutter while driving. It just roled 52K and the dealer cannot understand the issue. Later, after the check engine light came on I took it to a mom/pop shop to find codes. Several codes came back..downstream O2 sensor,
injectors 1, 2, 3, had a code plus indicated lean. I assume this means burning lean/rich. I re-set my check engine light so I could test again after if came back on has there was a smushed hose (which one I do not know). Engine light did come back.. had a short version of a D.test done that did not indicate any issue with o2 senors.
Now my values have started clattering while shifting or going uphill. I fear this is a sperate problem, but I hope it's being caused by whatever is actually worng with the car. This has been happening for months and I am taking small steps to address all possible issues.. Spark plugs were changed today..
Could this just be a injector issue?
What's all the comments about ECM? Was there a re-call? What are program updates for ECM? This concept is new to me.
Are the o2 sensors seperate from the throttle and mass flow senors? I believe the 01 4cycle, manual has 4 total sensors.
This was defective manufactor year and we were part of the class action..many many small things have broke.. larger things like timing jumped..timing belt snapped @ 26K..pullies popped...spark plug wires burnt up at 32K...best and most amazing issue was the clutch burning up two weeks after buying this junk.. I've only driven manuals my learning must have burnt it up..whatever nonsense...!!!! even a begininger chouldn't burn a clutch system in under 200 miles on a new car!!!
I can't burn the car as it's a second car for work... so please give me some idea's
since the dealer is clueless...
