details- 95 civic b18a ls hydro trans p75 ECU stock injectors, ignitions stuff, ect ect it hasnt ran for a few days. hoffman came over to take a look, he cleaned the connections on the dizzy and it fired right up. left it idling for a few minutes, ran fine, idled perfect. decided to take it for a drive, it was running good for a while. once it was warmed up, i got on it a bit, and it started missing past 3k or so ☹ eventually it just kind of started running like crap all together (missing, stauling, ect.) after it staulls it fires right up, and runs fine for a bit but eventually starts idleing down and dies. any suggestions? ---

but it runs fine until it gets warm, i was reading the coolant temp sensor can send bad info to the ecu causing the wrong amount of fuel making it run like poop once it gets up to temp? i was under the impression if the coil/dizzy/ignitor was bad it wouldnt run at all? also, plugs and wires are literally a few weeks old ---

Just let it sit for a few hours, tried to start it, it won’t. Pulled a wire, no spark. ☹ is the dizzy/coil/ignitor sold as all one unit? ---

Replaced the distributor cap and rotor, plugs and wires and it was fine after. I’ve always been told the coil is one of the last things to go. ---

sounds like ignitor. Very typical problem. however, it won’t hurt to try coild first, way cheaper than an ignitor.
