A few weeks ago i was going to college in my car everything was fine. after i left hours later my car from nowhere start to misfire and had some hesitation when accelerating i fix the whole ignition system because i thought i had electrical problem and after that i still had the same problem so i thought maybe i bent valves i did a compression test and got 210 190 210 190 i thought that was fair enough however a mechanic told me the results were irregulars and something might be bad in the head or in the block. the engine is b16A im already out of ideas so thats why im here. my question is the next one is that good or bad results for a compression test ? what is the specs for a b16a?

did you even check the spark plugs? Sound like a bad injector, if you already replaced the spark plug wires.

delsolb1695

Yh i did the whole ignition including sparkplugs

NVturbo

if they have been changed, it's likely one of the injectors is either clogged or bad. Your spark plugs will be an indicator of this

delsolb1695

Two sparkplugs have a good color the other two always came out black is that a signal of bad injectors?

Pull the CEL codes.

delsolb1695

I try it but no code came out i used a gasoline treatment on it and for a moment fixed the problem but when i asked for power the problem came out again and apparently gets worse the more time i used it

muellersfan

Is the SiR OBD1? If so, does the CEL work?

delsolb1695

Yes is Obd1 and yes it works as far i know. theres is any way to test the cel without using another person cel? just to be sure

muellersfan

Turn key from OFF to ON(II). Does the CEL turn on and then off after 2 seconds?

delsolb1695

yes

muellersfan

What exactly does this mean? Post details.

delsolb1695

I have replaced everything related to the spark Cap, Rotor, Cables and the dizzy itself and spark plugs

muellersfan

Brands purchased?

Did you adjust the ignition timing?

delsolb1695

don't remember the brand some pep's boys ignition and i call a technical honda guy for the timing and he told something might be bad in the engine due the results in the compression test he didn't did the timing after idk why. tomorrow I'm going to get the mechanic to do it i just want to be sure is nothing mechanical my question is are those results normal or are bad?

muellersfan

Hook up a timing light with the service connector jumped. You must set the ignition timing after replacing a distributor. The engine would hesitate if the ignition timing is off.

And aftermarket distributors are generally crap for Civics.

delsolb1695

Ok i will

muellersfan

The compression results don't concern me. I think your mechanic is exaggerating or trying to enrich himself, possibly dishonestly.

delsolb1695

Nice i will do the timing and check how it goes

190-210 across the board is fine and would not cause a misfire or no start. The problem lies elsewhere as muellersfan believes. Check the distributor timing but also check the spark. Spark must be blue-white in color, if it is orange then it's not good. Do your spark plugs smell like fuel if you crank it over for a bit then take them out?

If they smell like fuel, your problem is likely ignition related.

If they don't, the problem is likely fuel related. Try spraying some starter fluid into the intake manifold (throttle body open) while someone cranks the car. If it starts and runs while you're giving it starter fluid, the problem is definitely fuel related.

Check that your pump is priming by opening the fuel cap, putting your ear to it and having someone turn the key to ON. You should hear the pump hum for about 2-3 seconds. If you don't, it's a bad fuel pump.

If it hums, you need to make sure you have gas. Try putting gas in, even if the gauge says full. I ran out of gas once because of a faulty gauge that stayed on full constantly, little did I know when I swapped clusters that I only had 1/8th tank to start with, lol.
