I just purchased a 95 classic for my son. While driving it home it started to sputter ang shake. The vehicle sat for over a year so I think the fuel may be bad. It didn't have much gas so we added some (1/4 tank) of premium and a bottle of injector cleaner. It continued to have problems sputtering and stalling. I changed the fuel filter yesterday and it is still doing it. Any hints?

Might be time for plugs and wires.

I'd first siphon the gas tank as empty as possible and put in 5 gals of fresh. Should be no need for a fuel dryer additive since the gas you get will probably have ethanol anyway (combines with water). Then run it to use the old fuel in the lines. If it doesn't straighten out in pretty short order plugs would be changed next.

Plug wires can be checked with a multi meter...so can coil packs that I THINK your 95 has.
Any check engine lights?

Ok. I will clear out the tank and try that. Thanks

Only when it's sputtering. When the sputtering stops the engine light goes out.

Most of the discount auto parts stores will scan that code for free if you can make it there. It might say "random misfire" or maybe you'll get "lucky" and it will say something more specific like cylinder 4 misfire. If you have time I Ebayed a bluetooth obd scanner for like $10. Works great on simple codes but it doesn't read ABS problems or my buddy's Cadillac stability codes. Still, it was AMAZINGLY cheap.
Getting that ancient gas out is a good idea either way. I wonder if changing the fuel filter is called for.

empty all the fuel, change the fuel filter, and refill with fresh fuel! give that a shot and if it still sputters, check fuel pressure at the rail and for any vacuum leaks.

Do you have any maintenance history available on the car? Others have already suggested everything I would say... replace fuel, scan codes if applicable (it will probably be a misfire), and replace plugs/wires at your first availability. All of those things should improve the functioning of a vehicle that sat for that long unmaintained. Also check out and clean the throttle body if it needs it (I'm sure it will). Here's a pictorial write-up on the TB cleaning. Also check out the stickied "How-To" thread at the top of this forum section, which covers a lot of potential issues you might encounter. |
