Most vehicles are designed to run on 87 octane, unless specified different in the owners manual. The knock sensors on your engine will detect an engine knock and advance or ****** the timing accordingly. If your engine is spark knocking, your "Check Engine" light should be on detecting a faulty knock sensor, hope this helps, Gary

Hard to strat in morning haen in cold weather and sometimes stalls at stop sign or stoplight


Change the plugs and wires. In the winter use 5w30 oil and gas line antifreeze.Use high octane over 87 gas.If there is a cap and rotor change them.That will make a deference.

Was told to use premium 89 octane gas only this true?


This is true. The only time you need to apply gasoline with higher octane is when preignition is present. If it sounds like marbles are bouncing in your engine when you are driving then get higher octane. However if the car is in good mechanical condition (cooling system, oil serviced regularly) then 89 octane is perfect.

junk in fuel tank, injectors probably got a little resticted. How bad was the gas? hook a hose to the fuel rail and bleed most of the bad stuff out of the system turning key to on position to activate fuel pump. The pump has a screen on it in tank but thats alot of work to get to. A little injector cleaner or octane booster would be an advantage in the tank

Hi, as with most of my older customers they were driving when higher octane fuels were needed so they think that is still needed today. Your vech. only requires 87 octane it was it will run cooler and get better fuel mileage using 87. Enjoy your new car.

96 Buick Century can't pass imisions code P1441


P1441, EVAP Emissions System Flow During Non-Purge.
you seem to have an evap problem these problems are hard to diagnose sometimes it can only be the gas cap or maybe rust around the seat of the gaz cap
get the code erase and see if it comes back on and if it does check gas cap and arroung the filling neck if there is rust if no visible rust apears you will have to get it check with smoke to see where it leaks

hope it will help you

Have a great day
