If you have spark, crank sensor is working properly. You really should be checking spark with an actual tester. Not enough spark or not high enough a voltage can cause the same issue. As suggested, also check compression on all cylinders.

Eric, can you chime in? Anyone?

I checked. 3 times for vac leaks. Listening and with carb spray at all points. Unless i missed some spot which is doubtful. I also dont think its a vac leak, i feel as if it would be present when its cold like right at startup. And it wouldnt be switching back and forth betweem open and closed loops. I feel as if a vac leak is or it isnt. Correct me if im wrong but ….
Again. From start up ,course of events is;
START UP
Open loop(cold engine) quiet motor,some bearing noise from the tensioner,no real vibration or miss.
Warms up,hits closed loop for about 3 minutes,runs like crap. Missing,bogging,black smoke. Then itll kick itself back into open loop.

Fyi when i first bought it i had an hour drive home on the highway and the thing ran mint at highway speeds. Problem is really noticeable at idle only. Higher revs or speeds ,all i hear is exhaust leaks 🙂

I wouldnt bother filling it. If youre able to do it without messing with anything for too long, disconnect it. Call it a day. No sense in wasting money

Both precat sensors stayed around .6v. Bank 2 sensor 2 actually came up to 1v but then shot back down. I took a video i wish i could post here but it seems too large

Ideas anyone?

[Kenny]

Check your axles as one of the guys mentioned. They can easily be inspected visually (check boots for grease leaks) or by feeling. Check for play. A little Side to side movement is okay vertical play is a no no.

Sticking caliper. If you replaced the caliper with an reman. Check the brake hoses for kinks. Its possible that left rear hose had an obstruction.

How long has he had the Civic? When did the problem start? Check your grounds in the engine bay, does the main relay click when you turn the key? Force ground the main relay and try again.
