Barts. Posted May 26, 2015 Share Posted May 26, 2015 Hi there, so I'm the owner of a 2001 wrx as of last week. Wanted one for a while but family and work have got in the way. So just a newbie question really where do I start with engine mods. The car seems ok just a little judder/misfire/ hesitation at about 3500rpm. Car is standard apart from a Bailey dump valve Samco hoses and a new walbro 255 fuel pump. So I guess I'm just trying to eliminate the hesitation before upgrading anything. Any ideas? I leave it with you. Thanks for allowing me to join your group. I hope to learn all I can about my new car. Quote Link to comment Share on other sites More sharing options...

Tidgy Posted May 26, 2015 Share Posted May 26, 2015 Welcome. I expect its the dump valve casuing it. can you take it off and see if its improived without it? Has the car been mapped at all? Quote Link to comment Share on other sites More sharing options...
Barts. Posted May 26, 2015 Author Share Posted May 26, 2015 No other mods. I'm unable to read codes until my cable comes tomorrow. Can't take d/valve off as I don't have to old valve. Thanks guys will no more tomorrow when I can connect car to laptop. Quote Link to comment Share on other sites More sharing options...
Barts. Posted May 27, 2015 Author Share Posted May 27, 2015 Just one more question guys. What coolent do I use in my car. Going to flush the system this week. Quote Link to comment Share on other sites More sharing options...
stants Posted May 27, 2015 Share Posted May 27, 2015 Make sure it's silicate, phosphate &aminate free, 90% of coolants are these days but etheleyne glycol stuff contains silicates which eat the water pump impellor , vest bet is getting a longlife O.A.T coolant, most motor factors sell it and Just do a 50/50 mix.

BIGD Posted May 27, 2015 Share Posted May 27, 2015 When was it last serviced ? Sent from my iphone using Tapatalk Quote Link to comment Share on other sites More sharing options...
Barts. Posted May 27, 2015 Author Share Posted May 27, 2015 Last month but no mention of coolent change on bill. Quote Link to comment Share on other sites More sharing options...
Barts. Posted May 27, 2015 Author Share Posted May 27, 2015 Right guys got my laptop cable today. Checked for faults no recent faults found but did have a cam shaft sensor message saved. Is this an issue and what do I need to check. Thanks again for helping me out. Quote Link to comment Share on other sites More sharing options...
BIGD Posted May 27, 2015 Share Posted May 27, 2015 The coolent wouldn't make it run rough. If it's been serviced then I would check the HT leads and listen if there is any loud ticking from the injectors ? If the crank sensor fault is not there now it should be ok ?

Gaulson Posted June 1, 2015 Share Posted June 1, 2015 Might be a MAF problem, could be worth just giving it a clean. It's amazing what problems a dirty MAF can bring. Quote Link to comment Share on other sites More sharing options...
Barts. Posted June 1, 2015 Author Share Posted June 1, 2015 Is there a walk through on how to clean my maf on this site. Cheers. Quote Link to comment Share on other sites More sharing options...
Gaulson Posted June 1, 2015 Share Posted June 1, 2015 Don't think so, I watched my brother in law do it (he's a mechanic) and he took the MAF off and sprayed electrical cleaner inside. Then waited for it to dry out before plugging it back in, worked a treat for me. Quote Link to comment Share on other sites More sharing options...
Barts. Posted June 1, 2015 Author Share Posted June 1, 2015 Just one more thing for today lol. Is my diff oil and gear oil the same I can only find 2 dipsticks Subaru manual says there separate but I can't fine any more dipsticks. Quote Link to comment Share on other sites More sharing options...
Barts. Posted June 1, 2015 Author Share Posted June 1, 2015 This is the front sorry. I know how to check my rear diff oil. Quote Link to comment Share on other sites More sharing options...
stants Posted June 1, 2015 Share Posted June 1, 2015 Yes mate the dipstick for the gearbox is also for the front diff, it's a combined unit, it also acts as the fill up hole for the box oil ! Rear diff you'll have to undo the top nut on the backside of the diff as you look at it from the rear, should be just about level with the hole if the levels correct Quote Link to comment Share on other sites More sharing options...
