Hi all,
I have a '90 BRG 1.6 V-Spec that I absolutely love to bits, but it has an irritating lag when accelerating...and it often pours out smoke from the exhaust when I put my foot down...but it then seems to 'clear' itself, or 'release' after about 4000rpm, and it then feels like the sporty car it should do!
There is also a vibrating buzz or 'ring' when accelerating hard, and on tickover at cold it often has a rhythmic squeak (which my better half tells me is proabably a belt squeaking) but sometimes the squeak is there, sometimes there is no noise at all. No difference between a warm engine and a cold one, either.
Any ideas what it can be/how I can get rid of this lag?
We have removed the cat, changed the air filter, new sparks, HT leads, checked timing and belts, changed oil/filter, changed O2 sensor, and checked the ECU but no errors...
All kind advice much appreciated!!!
