hey guys,
got a problem thats driving me crazy, 2months or so ago i changed my entire distributor on my dc2r with a brand new item and my o2 sensor.
(i changed the dizzy coz it was finished, my car was misfiring ect)
then with the new dizzy i went to heathcote drags, got a shocking 1.8secs slower 1/4mile.. car feels overall shit and laggy. no real pull.
my rpm tacho jumps all over the place as well. the car hits the limiter at like not even 7500rpm. sometimes it just randomly jumps at like 3000-35000rpm. (car idles perfect)
i went to a mechanic and he advanced the timing on the dizzy, the car was back to its old self, running like a champ and revd hard all the way too 9k. then on the way back from there the tacho started playing up again. when the tacho plays around the car is slower.
what could be the problem? ICM in the new dizzy is a nugget from factory?
fuel economy is good, starts fine, engine compression is-
cyl 1 - 256
cyl 2 - 246
cyl 3 - 249
cyl 4 - 240psi
oh and when changing gears from 1st to 2nd the revs drop to exactly 6,000rpm (previously around 7200rpm)
and from 2nd to 3rd the revs drop to 5500 ( previously 6500rpm)
