I have an 86 CRX Si, with a blacktop swap (D16a1). Just got it running a couple days ago. Before I had the exhaust hooked up, it was open header. It was popping and backfiring out of the header, and still no power. Now, im pretty sure its still backfiring inside the header, which is the noise, but why is it popping so much, and no power, and idling high?!? Cam timing is dead on, ignition timing hasnt been touched yet, Still working on the vacuum part of it. Before I had everything hooked up correctly, but now I am working to delete the unnecessary stuff, such as some of the solenoids, and the charcoal canister (which is debatable for some people). Just wanted some input as to what yall think the main issue is here. Also no CEL is on, and it seems to run better the higher the RPMS (still no power as far as idle goes, just revving wise), freshly rebuilt motor and head just got back from machine shop. New plugs, new wires, new cap, new rotor button, new fuel filter, new gas tank, new Walbro fuel pump, cleaned the eavc, Lucas injector cleaner in use now, all grounds are good, any ideas?
