Q:

1996 Sebring Hesitating (Misfiring) & sometimes stalling: on 1996 Chrysler Sebring

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
1996 Chrysler Sebring LXI
2.5 L - 6 Cylinder
VIN = 3C3EL55H1TT259374
Bought car new in Dec 1995, has only 95484 miles…

Getting code on Scanner Tool = Acteon ‘AutoScanner Plus’ - CP9580

P1391 = Lost of Camshaft crank
Info’ from Scanner Tool; what could cause this problem:
1) Replace Crankshaft Position Sensor (CKP)
2) Replace Distributor Assembly
3) Replaced Flex Plate (fly wheel)**
4) Repair CKP Sensor Connector
5) Replace Powertrain Control Module (PCM)

Parts Replaced (in order):
1) Crankshaft Position Sensor (CKP) (2 times) --- After 1st (aftermarket) sensor change; hesitation went away for about 1 year…
2) After 2nd (CKP) sensor (Chrysler part); hesitation restarted after driving only a few miles…
3) MAP Sensor & its connector --- At this time I was also getting code ‘P1296’ (No 5V to MAP Sensor) Hesitation restarted after driving about 30 miles (have not gotten this code P1296 since …
4) Fuel pump --- Was recommend to change… Again hesitation started after a few miles….
5) Distributor (Camshaft Sensor built in) with a new one aftermarket…
6) Sparkplugs & their wires at the same time as the distributor was replaced; with no help…
7) Powertrain Control Module (PCM) – Ran for a few miles then the problems come back very intermittent…

Also I have ohm-out wires (harness) from sensors to PCM; moving harness to see if there is an intermittent open, looked OK…

Currently:
The car seams to hesitate more when:
1) Moving from a slow to a faster speed or going uphill (engine under load) …
2) Also accelerating from a stop…
3) The ‘Check Engine Light’ does not come on all the time when the engine hesitates…
3) When the engine does stalls-out (which is very intermittent) it always restarts with no problems…
4) **I cannot believe the Flex Plate would be the problem… What do you think?
Does anyone think it could be the timing Belt?

Sweep test TPS. Several times! Dont sound like a mechanical part like flywheel or belt. Check vacuum to MAP sens. Codes now?
Thanks for your time & reply.
It is currently only getting one code P1391(Lost of Camshaft Crank). Agan this problem is intermittent.
A sweep test on the TPS I assume is moving the sensor (accelerator pedal) while measuring the resistance or is it better to measure the voltage without the engine running?
