Engine Tech / Distributor Install - LOST rotor location
I was rebuilding my distributor and messing around with the thermostat in my 88 XR-7 5.0 (stock) and I realized I forgot to mark the position..some time has passed and not sure where it should be...

..Any ideas on how to make sure I'm on the correct gear tooth or just go and move it one tooth at a time until it starts and runs well?

Thanks!

Engine Tech / Update:
Well,

Replaced the thermostat because I already had it apart and it was a cheap replacement, but tried to START and had following issues:

-Car started and ran ROUGH (shaking, studdering, and sounding like its struggling to live..was somewhat unreactive to throttle) for 20sec before I just shut off..very unusual considering it usually starts and runs great up until it dies...ran like shiznit

-Car will no longer start following this incident: turns over, then just drains battery; can hear starter and fuel pumps kick on...

Because of this I am charging battery overnight and HOPING to check codes tomorrow, as I can not do so with out it running/warm

Engine Tech / Stumped: 88XR7 Starts but stalls at temp - HELP!!
i can't really check the codes because it only gets a check engine after it stalls, when it won't read anything...

..replacing the fuel pump pick-up and thermostat this weekend and going from there...will keep updated...thanks for the probable causes!

(yep, in rochester currently..originally from alden)

I have an aftermarket temp gauge with numbers 'cause my dash temp gauge shiznit the bed...I have a fail-safe thermostat in currently so I dont think it is stuck closed, if anything its stuck open because I ran the car with the radiator cap off and there was a constant flow of fluid....

Engine Tech / more...
it seems to loose power before hand, but it has happened before when it just dies as well...

..also, when it was about to die once (check engine came on and it started to stall/die out), i gave it some throttle and it kicked back and apparently had sooty exhaust but then it died again a couple minutes down the road...

..I have been noticing it idling a little rough after giving it steady throttle to 3500rpm and letting off..it will shudder a bit while idling but then seems to smooth out..back and forth, shudder-smooth-shudder-smooth, etc...not sure if this is related to the stalling out problem

addl. notes:alternator is 1y6mo old, pwr steering pump is 2mo old, and intake plenum, vacuum lines, and valve cover gaskets are 2mo old...

I have an 88 cougar XR7 that is stock except the air silencer removal...Recently, the car will get up or near running temp. and will stall out...Some times I will be able to get it started again, but it always dies again shortly after that (1-2miles).  After that, it will rest for 45mins or so and will start up after that. 

The problem seemed to start when the car would not start after shutting off the engine following a longer trip on thruway (1 hr drive), and slowed progressed to where the car would randomly die while driving....

I have tried a number of things:
-Coolant flush
-Checked plugs/wires
-Cleaned distributor cap/rotor
-New Ignition Control Module and Pick-up coil (the part inside the distributor)

I just took it for a 3 min ride after rebuilding the distributor and letting it warm up to about 150deg...it stalled and would not start after pulling in a driveway to turn around.  I put the car in reverse after pulling up and it seemed to die then.

Any ideas?? This one has got me stumped..

Thanks in advance!!
