Blue smoke but no lights on the problem


blue smoke on startup is generally from worn valve guides or bad stem seals on same (not really terrible as long as it stays the same) It will run rough for a minute 'till the oil in the cylinders is cleared out. Service engine light is pretty much on its own timer and does not mean anything but it's there to annoy you into going to the dealer. If O2 sensor was bad, it would eventually put the red check engine light on.

Runs Fuel rich-miledge is down 50%, exhaust smells rich


Needs to be put on scan tool to get the readings of the o2 sensor and tps sensor and see if they are correct. Also check for stopped up converter.

1990 Buick Century 3.3L Check Engine Light comes on, stalls.


Need to check for fault codes. Possibly a faulty sensor causing the fuel system to run rich or lean.

1991 buick park avenue will not stay running and runs rough


I think you got your answer to the alarm issue. I had the same problem with rough idling, lack of power, and the chugging that occured when going up hill. I have a 1991 Park Avenue with 190k miles. Fixing the catalytic converter helped, but the real problem was in the ignition control module. It seems that older buicks will heat these units to the point that the glue inside melts and eventually exposes the electronics. Look for glue or exposed wires below the ignition coil. It's a $100 part that you should be able to change yourself. I hope that helps.

90 f150 5.0 has issues


If your check engine light is on, you will need to have it tested to see what codes have been stored. The light will stay on until it has been tested and codes cleared. Disconneting the battery for five minutes will also reset the light, but if the truck is running rough, you don't want to run it like that. It could cause severe damage to the engine. Best bet is to get it tested and correct the underlying problem before it costs you big bucks. Good Luck
