as for ideas, well no but my bro (SIKSIX) had the simular dramas on his car. he changed fuel pump, removed unichip, checked fuel reg filter, cleaned injectors, new ign coil, leads , plugs, oxy sensor, cleaned t/b and map/
maf?, done a leakdown test.
the only thing he wanted to do was change the
ecu. but never got around to it, cause the christmas storm got to it and now its in some wreckers yard rusting.
Hope that helps.
