[T3] Running rough, etc.

[J. Jonik]

Thanks for tips.  Oil light does (now) work when ign. is "on", oil level OK, timing right on (but know nothing about "dwell"), pressure sensor hose ok, ...so...if no rain, will check valve gaps and put in clean fuel filter.....but...one spark plug may be trouble...worried that something may have happened to the threads the last time plugs were checked...and I don't care to replace a head, or know how to install an insert.   I know now to use graphite on plugs, not oil, to ease insertion and removal.

Does the oil light work when you just turn the key ON?
Check engine oil level.
Do you have a broken overflow hose (under the RF fender?) If so there 
may be water or dirt blocking the fuel filter.
Check the pressure sensor hose to make sure it's still connected on 
both ends.
Check the valve clearances.
Check the dwell and timing.
Take a look at some of the spark plugs.

Test the fuel pump relay by using a small jumper wire to jump across  
it to see if that makes the pump run better. If so, there might be a 
problem with the relay. (Don't jump on this as a possibility without 
testing it. It's a long shot.)
