Urban Coyote Posted May 20, 2008 Share Posted May 20, 2008 I was hoping someone could help me out with this. My ’98, Subaru Legacy, 2.2, standard transmition has been stumbling a lot lately on acceleration when running cold. It’s not noticeable or present when the car is warmed up, but it stumbles in all gears when cold. I recently changed the air filter and the problem went away for about three days, but now it’s back and just as bad if not worse than before. The gas mileage does not seem to be effected that I have noticed. Oddly enough I did notice a stumble/backfire? …once while on the highway… Any ideas? No CEL or other lights so far.

Dickensheets Posted May 20, 2008 Share Posted May 20, 2008 I would do the plug wires first. I had a similiar scenario. Cured. Link to comment Share on other sites More sharing options...

Urban Coyote Posted May 21, 2008 Author Share Posted May 21, 2008 Thanks! Plugs & wires are on the to-do list as is a fuel filter which I already have. I've never changed these myself yet so am waiting for a time when my brother can come out and give me a hand and show me how it's done. The stumbling/bucking on acceleration is not something that has started gradually. One day I went to go to work and there it was, out of the blue. I'm keeping my fingers crossed and hoping that a tune up will cure what ails my roo. Urban Coyote Link to comment Share on other sites More sharing options...

LosDiosDeVerde86 Posted May 21, 2008 Share Posted May 21, 2008 i had what sounds like almost exactly the same thing happen to my 96 2.2 leg. it ended up being the MAF. It was getting water on it some how causing it to make the car stutter. Link to comment Share on other sites More sharing options...
Urban Coyote Posted May 23, 2008 Author Share Posted May 23, 2008 Thank for the feedback everyone! I bought NGK v-notch plugs the other day but the predominant wires available around here seem to be bosch. I can't find NGK wires. Is it going to be a big deal to use bosch wires with the NGK plugs?

davebugs Posted May 23, 2008 Share Posted May 23, 2008 If nothing else try one of the mail order places and get Subaru wires sent to you. I'd do that before settling for aftermarket wires. Then again I haven't had much trouble with aftermarket wires on 2.2 but I have on 2.5's. Still while you're trying to solve a probelm I'd order some genuine Subaru wires and install them when they arrive. Dave Link to comment Share on other sites More sharing options...
EVOthis Posted May 23, 2008 Share Posted May 23, 2008 not sure if your model year calls for platinum plugs or not.....but i have a 96 legacy 2.2 5 spd. and i put platinums in there and my car ran horribly...once i switched out for regular champions the car never ran better.....just mentioning it....

Urban Coyote Posted May 23, 2008 Author Share Posted May 23, 2008 Uhg, the only thing is I HATE going to the dealer for parts....they mark them up so much it's ludicrus. Ahhh Haaa....just called the dealer and found out that the "Subaru" brand plugs and wires they sell out of the dealership are NGK brand Soooo.....I'm on the right track Link to comment Share on other sites More sharing options...
etc Posted December 8, 2008 Share Posted December 8, 2008 STart with a full tune-up Plugs Wires Fuel Filter PCV valve I kind of have a similar situation with my '98 2.2L, it kind of stumbles or misses a bit in 2 to 3 gear. I will plugs and wires and fuel filter. Are there any other ignition parts that are replaced during the tuneup? This doesn't have a distributor, does it?
