need some help we have a b20 with a vtec head and its having problems with the ignition. when i start the car everything is normal until i rev it up to 3500 thats when the tach goes crazy and the idle goes eratic. when i drive it the car stalls after 3minutes then it wont start for another 2 mins.

we already replaced the distributor, plugs, ecu, main relay, soldered all the connections and still the problem is there. HELP.

Does this have anything to do with the injector relay i just installed. im currently using DSM 450cc's on uberdata

 

solved the problem. turned out the msd plug wires where the culprit after checking the harness and found nothing wrong we decided to pull the plug wires out and put in the stock wires...problem solved
