do a diagnotic first to see if you have any codes...
if you arent sure how to do this... get a piece of wire and put one end into into T1 and the other into E1
(the diagnostic box is located by the driver's (if your car is us spec) side strut tower, little black box with diagnostics written on it
)
turn your key over to ignition and watch the engine check light... see how many times it flashes
eg 14 would be
flash (1 sec pause) flash flash flash flash
23
flash flash (1 sec pause) flash flash flash
if there are more than one they will be listed in consecutive order ie. 12 14 23 34
there is a 2 or 3 sec pause between codes... when the codes are finshed there will be a 4 second pause and they will restart flashing
let me know what codes you've got and we'll go from there
