Concorde 2002 Limited Edition 3,5L - Error Codes, Choking and Check Engine Light
Hi,
Problem with a Concorde 2002 3,5L V6 (56,000 miles). Vacuum leaks and coil (cylinder 1) have been fixed. After that still experienced misfire cylinder 1 (p.0300 and p301). Spark plugs and oxygen sensor were replaced. Check engine light keeps coming back on. Now => O2 sensor codes -- p0030, p0036, p0050, p0056.
When engine is cold, there is no problem. After restarting, I lose power when accelerating out of low rpm and steady throttle (2/3 gear). As if he's choking (see video). After I have pulled it through the "choking" (giving it extra fuel), it seems to recover and give no problem. Until I restart the engine.
Any ideas?
Thanks in advance!

Concorde 2002 3,5L V6 (58,000 miles). Vacuum leaks and coil (cylinder 1) have been fixed. After that still experienced misfire cylinder 1 (p.0300 and p301). Spark plugs and oxygen sensor (asked my mechanic what brand) were replaced. Check engine light keeps coming back on.

When engine is cold, there is no problem (although this morning it kind of choked). When engine hot, after restarting, I lose power when accelerating out of low rpm and steady throttle (2/3 gear). As if he's choking. After I have pulled it through the "choking" part (giving it extra fuel), it seems to recover and give no problem. Until I restart the engine.
