Engine Mechanical problem
1997 Subaru Impreza 4 cyl All Wheel Drive Automatic 185400 miles
I am experiencing cylinder misfire in cylinders 1
& 2 (according to the computer). It has been to the
Subaru dealership 3 times and they cannot figure it
out. Part of my problem is that when I even get the
car close to the shop, it won't misfire.
They have changed all of my spark plugs, did a full
tune-up, check my fuel filters, lines, et cetera.
The problem started about a month ago. I started my
car in the middle of the day to go to a meeting and it
started to shake and it sounded funny and the check
engine light was blinking. I gave it a little gas,
put it into reverse and it stalled out. I turned the
car off, waited a little bit, turned it back on and it
was still doing the same thing. I started to drive
it, but when I gave it gas it would barely go
anywhere. I putted for about 25 yards and then it just
switched out and was running like normal. I came out
of my meeting, started the car and it did the same
thing and then just switched back to normal. I drove
it to the dealer, they looked at it and told me it was
misfiring. My spark plugs needed to be changed badly
(I already knew this), so they changed my spark plugs.
The car ran fine for two days, then it happened
again, except this time, it wouldn't kick out. It
started to smoke and smell funny, so I pulled over and
called a tow truck. They towed it to the dealer, the
dealer kept it for 5 days and tried everything they
could on the car, but it wouldn't misfire for them and
they couldn't figure it out. I got my car back, it
ran fine for a few days, then it did it again. I
started to drive it to the dealer, I got about 10
miles and it kicked out and started running normally.
I dropped it off again, but they were still stumped.
I finally gave up bringing it. But now the car is
misfiring almost every time I drive it. Yesterday, I
let the car warm up for 20 minutes, drove it around
the block 4 times and it still wouldn't kick out.
Today, I drove it to work and back from work and it
still wouldn't kick out. But, when I started it
tonight, it was fine. I am deeply frustrated. I feel
like a crazy person because the car doesn't seem to
act up for the mechanics and because when I have to
drive it it is shaking so badly it almost makes me
sick, it smells horrible, smokes and it barely accelerates and I can only get it up to about 40 mph.
How is the engine oil and coolant levels? Does this engine have spark plug wires or coil packs on the plugs? Were the wires or coil packs tested or changed?

Hey man, I have the same exact problem, except when I changed my spark plugs and my coils ( which are coil paks) the engine stoped missfireing while running on normal driving bases, but when I push it to get some speed, thats where it start misfireing and the accelration dies on me. I tried changeing the ECU, fule filters and pump, coils, spark plugs, sensors, even the air filter. Nothing worked, cant say it didnt get better, but not like it used to be. I still cant get my turbo power back.
