New Subaru Fan Posted January 6, 2010 Share Posted January 6, 2010 Hi Guys, When I accelerate very fast she starts to jerk really hard http://www.thesubaruforum.com/forums/images/smilies/smile.gifIn the beginning we thought it could be because of the older turbo design but the guy I met yesterday told me his Legacy GT (same as mine) accelerated smoothly and he even didn't know what I was talking about.So now I'm thinking there might be a fuel issue (pump, filter, injectors or something like that).I really need to address this issue as I don't want to ruin the engine after we replaced HGs etc. Has anybody ever had this sort of problems or has anyone an idea?

old legacy GT Posted January 21, 2010 Share Posted January 21, 2010 is your car from somewere else than the states?? I thought all the old legacy turbos had the ej22t the 2.0L engines are twincam with bigger turbos! was the engine swapped in there? mine doe's that but its got some issues as I swapped in a ej20g and its running off the 22ts ecu and its also got a leaking brake booster! so theres a few things that are making mine do that but sounds like either smoe fuel cut or bad spark!! but ya Link to comment Share on other sites More sharing options...

The turbo is a factory one too and is an average sized one. Do you think our problem is somehow related to the brake booster? And what do you mean under 'smoe' fuel cut? There were even cases when my engine stalled for a second. I'm going to check my fuel pump first and replace the fuel filter. Let me know how you're fixing your problem.

old legacy GT Posted January 22, 2010 Share Posted January 22, 2010 I meant some fuel cut!! lol but ya did you try adjusting your throttle position sensor?? mine was really bad untill I had the Iac and the thottle position sensor adjusted proper to my setup!! but ya look for vaccum leaks!! but ya the american turbos were even smaller than the ones on the 2.0L's! from over there! I have an engine like yours swapped in my car it"s been kind of a pain!! but the car is kind of done so ya!! Link to comment Share on other sites More sharing options...

Jiranz Posted January 26, 2010 Share Posted January 26, 2010 Mine missed badly under load at 100,000Km due a faulty ignition coil. Two had hairline cracks in the neck area where the spark was leaking. I got replacements from a wrecker at that time because they were too expensive new then. At 400,000Km needed a full set as same fault happened again. This time three tested faulty. Had more money so bought new. Also change all spark plugs each time.Goes like new.

New Subaru Fan Posted January 29, 2010 Author Share Posted January 29, 2010 Thanks for your help, guys. Unfortunately I'll probably not be able to deal with this problem for the next couple of months Link to comment Share on other sites More sharing options...
