cheers guys, i got it started and yeah,.... i learnt my lesson. Im going to take the car to a rotary mechanic and get a proper tune. They do lots of work on the IPRA 13b bridgeys with webbers so i guess they will know what there doing... ill keep you posted.

just need some money, $110 an hour plus parts isnt fun, but oh well... you get what you pay for

Any update on this issue? I'm still suffering here... It really becomes undrivable in the range, I think it's getting worse. I just had the plugs checked and they were in great condition, cleaned them up too, still same problem.

A mechanic noted that my 1000cc primary injectors being run by the digitech series 1 pro ecu was not a good mix, could be contributing to my problem... I also didnt have a dizzy shield, but I've got that now and it has made no noticable difference.. He recommends I swap the primary 1000cc with the original secondaries and dyno... I forgot to bring up the issue of vibration - how could i forget?- theres a hell of a lot to do on my car :P

Any news would be great! Cheers

One time i worked on my car and drove it and felt a nasty vibration, then I remembered that i for got to tighten the clutch fan....opppsss... took care of that. Also I had an SE that someone torqued the bolt till it broke, and it would get a nasty vibration @ certian RPM's then I removed it and put a new one and took care of that problem...but If you saying that the shifter vibs nasty then maybe the driveshaft...I thought I had a tranny mount problem then got that shaft balanced and new U-Joints....WOW....all i can say.

Talking No more vibratron! =)

Sweet as! All fixed now

The problem with mine was the transmission mount.
- 1 - There was only one bolt between the mount and the transmission
- 2 - A previous owner had the exhaust welded onto the transmission mount, pulling on it
- 3 - The rubber was rock solid and had slid out of correct allignment with the mount sleeve

My transmission output-end was pretty much touching the right side of the chassis, which really aided in feeling the engine through the car. It has made such a difference to fix this! Silky Smooth

I also found my universal joints have a little movement in them. What I didnt realize last time after rebuilding them was that you need to punch around the edges of the sleeves to hold them tight in place...

Hope this helps someone..
