I recently bought an 88 crx si. It has a D16Z6 Vtec head installed with a p28 ecu ,Zex cam and valve springs, New clutch installed including flywheel resurface,head on car has 50,000 miles and block has 150,000 ,car has projector halo headlights and a full pioneer and infinity system that will come with car. Other mods include OBX billet crank pulley ,Cold air intake,Msd blaster 2 coil and Msd pro cap and rotor with 7mm plug wires,Car has OBX header with custom 2.5 inch pipe back to OBX muffler angle mounted....now everything was going great until this morning, the stereo power is going in and out. I thought it might just be the power or ground or something. But now the rpm gauge and cluster lights are going in and out. I checked the battery and alternator and both are good...what else could it be?
