1986 Subaru Other

I have changed plugs cap rotor fuel pump and fuel pump relay. The car runs great above 1500 rpm but below that it stalls. The car is a brat with a 1800 turbo engine. I have also notice the voltage from the alternator is low but had it checked and it checks out ok. The coil just recently stopped putting out a spark as well. The distributor turns and there in 12v going to the coil. Please help with my electrical problems.

the first time the differeence is about 3 horus labour

my car did a similar thing ( its a 1996 impreza wrx 1996 dohc coil over plug type
i'm not sure wehter your vehicle has the idle control or not but if it has it would pay to make sure that it is well greased & turns freely or make sure that carby is not all clogged up

my other thoughts were to run some fuel additives & subaru upper engine cleaners through proberly at least two.

Alternator should be putting out at least 13.5 to 14.8 volt

also when replacing cap rotor etc the following should be replaced plugs, module, coil, leads as well as.


make sure that the

I forgot to say the following

this could be a fault within one of the parts which has caused the other to died.
