94 civic dx JDM D15B still hesitating after tune up
94 civic dx
JDM D15B
ok... my vehicle is still hesitating. it usually happens when i turn it on and drive out of the parking lot, when cold. after that, it runs like a dream. BUT it does happen when it is not cold.
i have a new ignition coil AND ignition control module... swapped out the ignition switch also. i have new plugs, wires, fuel filter... i have no idea what is wrong with it. it originally had a shut off while driving issue until i changed the ignition switch out, but now it is giving me this problem.

If it also does it at random i would check to make sure all the internals in the dizzy are tightened down good and check for damaged wires. Another thing it could be is a leaking map sensor. Im throwing this out as the first little bit that the car is running the o2 sensor isnt sending information until it reaches its operating temperature (Honda's use a map and o2 sensor to help deliver fuel instead of a maf) so check you o2 sensor to.

how do i check the map sensor?
also, how do i check the o2? i ask because i never had an o2 fail on me without a CEL showing up. i have no CEL, so i do not even know where/how to look.
my vehicle does idle a bit strange... but i think it is in my head. i will check this ... hope i do not have to purchase a timing gun. i am going broke here.

nope... sometimes, i wish it was though... so at least i know what the issue is.
yeah... but it isn't too noticeable. i think it is timing related.
