B;what is the promblem some one help???

 

If you have never changed your timing belt, you NEED to change it before the trip. As for the misfires, you have some work ahead of you. I'm sure its an easy fix, but exacting the problem can be troublesome. Tom has helped others with misfire problems, so I'd wait for him to chime in.

You only had a few oil changes by 174k? Oil change is due every 7.5k with the oil filter change every 15k.

 

since owning it in november ive done 3 oil changes ,and hopefully tom can help me figure out this issue

 

he will.. Tom will be here later on 2day or 2morrow morning

 

how old are the spark plugs? correct ngk--the 8 dollar ones?
realistically they last 100kmiles at the outside, most of us change around 70

timing belt, water pump, valve adjust, with egr port cleaning of intake manifold are all way overdue on your car
valve adjust for sure by now too--at 100 a few are off spec, but now,,several and farther
It makes a huge differance in performance, and gives a chance to clean intake manifold as combined labor

multi cyl misfire code is often just 1 bad coil
you can ck threads here for how to test,,unplug 1, start and ck idle speed, when you get one that doesnt drop the idle slightly--you found the bad coil

Reset ecu via clock fuse method when you install the new coil (any parts store) or move it around during testing
Expect that spark plug to be in need of new- will be fouled

saw a new way of cyl. testing on nascar- a crayon touched to each exhaust pipe as it exits the head, the one that doesnt melt it is dead!
or for the techie harbor freight tool fan, an infrared heat gun/guage- point and read anything

 

Why have you changed the oil 3 times in 4 months?
how does it look..tried seafoam in the oil before change yet

sidenote: regardless of any book- using a regular oil filter (not special amzoil type)
dont wait 15kmiles to change it- thats not a good plan over saving $5 now
When you do oil at 5000-7500 miles depending on your needs and preferance,
change the filter- its way cheap insurance by being able to capture crud.
If it gets full- it bypasses and doesnt filter anything more

if you are on the original timing belt--stop driving it-
get a gates brand set of parts for ~250 or acura brand thru vendor wholesalepartsguy for 350..-400 with the extra gaskets for v/c etc
See the 105 service diy and decide if doing it with your buddies or shelling out for several hours labor at a shop

look at the bolts on timing belt cover- any signs of contact with a socket or wrench 70kmiles ago?
It you start taking it apart and see the belt is ~new~,,stop- put it together and enjoy another year.

for trip prep - there are many threads with that title- search feature will help
