Before I drive it off a cliff anyone got any other ideas?.

Had a missfire/hesitation/idle problem for ages now. the car is a 93 wrx.

Had the following done:

1)Many sets of new plugs, and had them regapped.
2) ECU codes checked (no fault)
3) Earthing points stripped and refitted (no earthing mod)
4) Changed the battery (worked well for 3 days)

Anyone got any other ideas?. Could it be the ecu itself?. Am going to borrow a sti 2 ecu to see it works then. Or could it be the alternator?. Power seems to drop when the lights etc go on.

Any help greatly appreciated.

checked your coil packs ? they could be on their last legs hence the plugs getting a weak spark then you get the missfire etc.

as for battery wouldnt like to say could be alternator if it not getting any cherge back into it. its a try it and see at the mo.

see what others say.

also clean and check your maf sensor.

 

could be the coilpacks. apparently they were ok. worth a look though.
will see what happens with the ecu and go from there.

after 6 months of it i might sell it and get an m3.

 

m3 you will regret it especially when its raining

boo hiss boo iff you get one!!!!

 

at least it wont go wrong for six months at a time. as much as i love scoobies mine is pis**** off now.

hopefully it will get sorted soon.
