i have a 89 crx HF w/obd0 b16. it's been running fine with no CEL's and then all of the sudden it'll go dead while i'm driving. the CEL will come on but not blink. the ecu doesn't flash any codes. usually i can just turn the key off then back on and it will start up fine and i can keep driving, but today it wouldn't start immediately. i'd have to try for a few seconds and then it'd fire up. also, my main relay clicks sometimes when it's about to go dead. like a fast clicking noise while the CEL is on, then it dies. so far it hasn't happened while i'm going over 20mph which is kinda weird. also, sometimes the car will seem to sputter at partial throttle until i floor it, but this is pretty rare. at first i thought that was the o2 sensors reversed but when i switched them it got worse, so i put em back.

so here's my symptoms

-car goes dead with solid CEL.
-usually starts right back up fine.
-ecu not flashing any cel's
-main relay clicking (tried another one, did the same thing)
-only happens a few times a day at low speeds
-sputtering sometimes at partial throttle.

anyone have any ideas about what i should start checking? the no cel part is weird...


edit: took the car out for a drive earlier. before it warmed up it ran perfectly, but i guess when it went into closed loop it started sputtering at partial throttle. i had to floor it over and over just to get home. it will idle fine, but any throttle other than WOT, then it sputters. still no codes.
