Subject:      Cold Start Chug and Warm Stumbling
Content-Type: text/plain; charset="iso-8859-1"

Patient: '84 1.9l Digijet currently in hibernation

Symptoms:  When first started the van will chug at low rpms until it warms
up.  If you get the rpms up and hold them there is does not miss.  When it
is warm to the point of the fan kicking on, and in stop and go traffic, it
appears to be flooding itself because when I go to step on the gas it wants
to stall.

What I think it is:  I'm leaning towards the Temp2 sensor, and/or some leaky
injectors.  These injectors have 143k miles on them.  I also have some
pinhole leaks in the front exhaust manifod just before the flange and the
collector.

Items to replace:  Temp 2 sensor, Injectors, Front Manifold, and O2 sensor
(it's overdue anyway).

Could it be anything else?  I could not find any vacuum leaks on the motor.
The motor itself is a Fast German Auto rebuild with 25k or so miles on it.

TIA,
