Hi I am new to the Subaru scene and I'm in need of some help please. I own a wrx bug eye impreza I've owned it for bout 4 months and the 1st thing that happened that was under steady acceleration my car started to 'stutter' especially when holding a constant speed of 60-70mph when that happens the engine management flashes at me so i slow down to 50mph and its fine and light goes off, but about 15-20 mins later of driving the engine/emissions management light comes on permanently! I have send to try and get it diagnosed but they can't find a fault and just reset it but as you would expect the same things happens any ideas what the problem might be?

The 2nd problem is that when my car warms up it just goes strate to the H only when I stop at lights then pull off to bout 40mph does the temperature fluctuate to about normal but then nearly immediately it's back in the H. I first noticed this problem after a long trip on the motorway might be a coincidence just thought I'd mention it! Now my fans are working, there is the correct level off water/coolant and oil is correct. Once again guys any ideas why?

My car has got cat back exhaust and induction panel filter and has dump valve that's it no other modifications

Please help or can any of you recommend any where to take it in the stoke on Trent area?

Cheers

 

Thermostat maybe stuck open mate. Whatever you do tho mate do NOT put in rad weld, k seal or any stuff like that otherwise its bye bye engine. Potentially it could be early signs to head gasket failure however do check the engine oil and water too see if its mixed in the header tank. Is your overflow bottle topped up by your battrry qnd passenger side head light

 

Yes all the fluids are topped up I hope it's just the thermostat thats stuck open :s how do I check if the oil and water is mixed?

 

look in the water tank, where you would fill it with water,maybe remove the dump valve and see if it runs better.the stuttering etc.

 

The water tank on the top of the engine? ( how much water is ment to be in there? I haven't got an original diverter valve to fit I bought it with dump valve
