Subaru Forester 1999

Has the fuel filter ever been replaced?

No it's been a year

Did you change the plugs and wires or did somebody else change the plugs and wires in either case I would check the firing order just to make sure nobody crossed two wires put them on the wrong plugs

I just put spark plugs in and I replaced the filter on the side can't find one of the air filters and I smell gas the power stirring leaks at the top

It was acting like that before I changed

Has the timing belt ever been changed and how many miles does it have on it

The belt I changed was the certifying belt to the altanater

It has over 4500,00

So what do you think I should do

I think the timing belt skipped a tooth or two. If it has over 450,000 it's time for a new one. Might want to get a timing belt kit, that way you will have a new belt tensioner and idler pulleys.

Peter, a Subaru will simply NOT run if ignition cables are swapped, as they're two 2 cyl motors bolted together. Most of the time they won't even start. As well, it's unclear what the errant mileage answer is, but it's unlikely to be either 45 or 450k...ha! The fuel filter is in the tank with the pump, and is rarely an issue. 35J7R, your plugs and wires are probably ok; a CEL noting a misfire would come on if you hadn't tightened a plug or wire, or had an intermittent coilpack (common). The smell of gas is from one of the two small rubber connecting hoses on the front of the motor. Replace and/or tighten their clamps. This is a common problem on cold starts; with time and temp the rubber swells and tightens up, so you don't see dripping. But look closely...you'll see wetness under one of the 4 joints. The ps fluid leak is from a worn pump inlet o-ring under the return hose on top of the pump. Unscrew the 10mm bolt and gently pull up the hose/connector assy. With a pick you can carefully pull the small o-ring out of the top of the pump; see how it's squashed from round to flat or triangular?...or even cracked from age? Go to a hardware store and buy a simple 0-ring that's just a little bit bigger than OE. It'll work better. What's happening is that air is being sucked into the pump (cavitation), where it will be churned into a frothy mousse and really screw up your steering, so don't ignore it. If you see seepage on the top of the ps reservoir you'll know that you've already had one or more such episodes. A fifty cent 0-ring goes a long way here. Note also there's only one air filter...on the pass side. Why are you looking for another? Report back after doing this simple stuff, and I'll tell you how to inspect the t-belt in less than 5 minutes, as you probably do NOT need a new one just from your stated issues.

Note if owned a 98 Subaru forester and they do run with 2plug wires swapped, so will a ford escort, chevy spark, and honda accord and civic. They may not run smooth but do run, by the time u get to 2000 to 3000 rpms most anything runs smooth. And I personally know of a 1999 mercury sable with OVER 385,000mi and I've been working on cars for over 35 yrs.

That was ... I owned a 1998

And the p300 code is where the computer is trying to find #1 and cant so the computer turns off each plug 1 at a time searching for #1. Because the camshaft sensor is reading within tolerance but not working.
