99 civic ex misfiring

My 99 civic ex started misfiring the other day. I gave it a tune up in the beginning of the summer. I re changed the plugs, cap & rotor. But it still idels really low and sounds like it is going to bog out when I put it in drive. Any ideas?

Hi there, it could be several different things try these -check the idol air control valve first. try taking off with a\c going and with the a\c off and see if there a differance, if there is, i'd definatly have it checked or replaced. another idea is have the catalitic converter checked, if its clogged you would have bad acceleration,wont idol right, you can check yourself with a vaccum gauge, just connect it to the service port or where the pcv valve connects to the intake and crank up the car and watch the gauge, when you accelerate the vaccum will decrease and let off the accelerator, then watch the guage if it comes back to vaccum very quickly your catalitic converter is good, and if comes back slowly than you have a problem, its clogged

Misfires


there are 50 causes of misfire. (and flooding)
50
what we do is, conduct simple tests to find what is going on.
but first do that missed , 60,000 mile tune up, it might fix the problem
in FACT , tuneups are 100% designed to what, stop misfire.

my wild guess is it flooding.
are the spark tips (all) soaking in fuel , stalled?

thats one test, and is free, for any show with basic tools.

if you need more help tell engines option and country.

You are dealing with a misfire you will need to check cap rotor spark plug and wires, and inspect the coil.

97 Honda Civic shakes at start and check eng light comes on.


It looks like misfiring in one cylinder. That is why check engine come on. Misfiring can be due to spark plugs/wiring/worn distributor cap. Maybe also vaccum leak and clogged injectors (use injector cleaner).
