hi, good day,
i need some assistance as i am frustrated over my impreza and i do not know who can help or who can direct me to someone who can.
i have a 2006 local impreza 2.0 engine bought from massy. i bought the car from the previous owner in may 2015. for 1 month the car worked perfect. as soon as you touch the x it will shoot off, acceleration great and top speed about 190 km. as soon as i changed the rim and tyres it died. it had 16's and i put 17's, but the manual said i can make that change. it started to flat spot and go dead. it will crawl up small hills x to board. on flat roads as well, flat spot, dead, no acceleration. then suddenly it will catch a vamps and take off again but will soon die down again. on the highway 3rd and 4th gears no problems. it will fly. but it never worked again as it did the first month.i have tried to reset it, but it will work better just for about 2 days and then go back again to working horribly. i have been to 5 mechanics including those in massy. they said the changing of the rims will not cause that, just coincidence. i have changed new fuel filter with regulator. also the fuel pump. we put a gauge to check the psi of the pump and it held up fine- no problems.serviced the air filter. i changed the knock sensor. i replaced the air flow sensor. i serviced the injectors and throttle body twice at different mechanics. i changed the timing belt and tension-er and pulleys - all subaru parts. i changed the engine and transmission oils. i changed the spark plugs. sometimes on the highway the 4th gear will take long to go in and when i try to kick down, it will not and the same gear will run. the 1st and second gear will sometimes go in with a hard buck.i scanned the car at 6 mechanics! the ignition is rattling now and it is burning excess gas also hard starting. i have used premium gas, super gas, super gas with octane boost - all with same results. the last thing massy told me was that the timing kept retarding and they do not know why. one told me to change the computer. one said that this computer cannot be reprogrammed. one said it could be the harness.
i do not know what the hell to do again.
i heard from some others with this model that they have similar problems( not as bad as me though) with theirs and they never could find the problem.
does anyone know anyone else with this problem and they were able to fix it? do you know of this problem at all? do you know a specialist subaru mechanic who you can recommend? is there any thing you can tell me that can help me? i am really looking for help. if anyone of you can assist, i will greatly appreciate it.
thanks for your time again.
