What makes you think you have weak spark? You
need to pull the wire off of the plug and hold it close to a ground and then see
what the spark is like. If it is nice and strong and can jump a decent
gap, then the spark is more than likely OK especially after replacing all those
parts.
Has it been sitting for long? Since the computer
runs the fuel system, I would pop it apart and look for moisture or anything
burnt. The slightest power surges (like with a new battery or a battery
charger) can take out a computer especially an old weak one.
Apparently you are getting fuel, are you getting too
much? Check the cold start valve (5th injector) and see if it is p#ssing
all the time! It could also be getting the wrong signal from the temp
sensor.
It is also a possibility that the plugs are just shot from
being fouled so much unless you have replaced those too!
Have you gone through the bentley's troubleshooting
guides? Always a good place to start!!!
I hope some of this helps. We don't get a bunch of
GTIs in anymore so I am not super familiar with the CIS w/lambda system but it
can't be too tough!! Good Luck!!

Hi...it isn't the roc (haven't gotten there
yet), but my 84 GTI #2 that I'm
having the problem with (GTI #1's engine
is shot now). Anyway, I haven't
driven this thing in about a year. It has
the stock CIS w/Lambda and a high
compression 1.8L. It still has the
original electronic ignition (nope, no
knock sensor just yet). I have been
fighting with it for a couple days now.
Orignally, I put a fresh battery
in it and cranked it up. All was well. Then,
after starting it a few
times, it began to run like crap. I went through a
set of plugs, then
found the injectors to be clogged. After replacing the
injectors, it ran
great. Then, it stumbled and died...and would not restart.
I cranked it
for a while, then pulled the plugs to find they were soaked in
gas.
Obviously it has flooded out. I replaced the plugs again and got it
started...dialed it in somewhat and then took it to the gas station to
fill
er up. Lucky for ! me! , it's all downhill coming back from the gas
station.
After shutting it down, it would not restart...it had flooded out
again. I
pulled the plugs and let it dry out when I got home....I got it
started
again...it was running okay and I took it around the block. It was
fine for a
minute...then it started running like crap. I got it back home,
and I
attempted to get it to run better by adjusting the mixture, but it
was of no
use. It continued to run crappy...died a couple times. I was
able to get it
started again, but had to crank it a lot. It finally would
not restart and I
pushed it back into the garage to be messed with
tomorrow. So far I have
swapped the fuel distributor, airflow sensor
plate, injectors, and warm up
regulator with other ones I had to try and
figure this out. I also swapped
the wires, cap, rotor, and coil...just for
the hell of it. I'm out of ideas
here...anyone have any info that might
help??
PPPLLLLEEEEAA! AA! SSSSSSEEEEEE!!!!!!!!!!!!!!!!
