Hello , just kinda looking around for some ideas on why my 4runner is acting funny . long story short , after I've been in it for an hour or so , something kinda starts missing now and again . sometimes its there , sometimes is not . example. Its always after about 2 hrs of driving , ran fine all morning then I'll pull up to a light and the rpms start to get sluggish , it acts like its down a cylinder ,just barley staying at idle . then the next light it will be fine . its been about 2 months since its started . no check engine or anything. I've replaced the plugs , one cylinder's plug looked a little more black than the others. Still missing at some lights .
So yday I put some cheap STP gas cleaner in it and it ran great all day . I kinda ran it a little harder to de gunk the anything in the gas lines . so I'm starting to think injectors , probably the one with the darker plug . I'm getting ready to throw new wires and a fuel filter on in a few days . just wondered what other peoples experiences were with similar problems.

Second issue , I blew my high pressure power steering line to the RAC , any cheap fixes ? They wanted 650 or so at a shop to do it , parts were 300 . read a little about using hydraulic lines made at a hydraulic shop , haven't had luck finding any . well any ideas I'd appreciate , thanks
