1991 honda civic

I have a 1991 honda civic dx. I recently changed my oil. I have
always changed my oil in this car. About a week later I pulled one of
my spark plug wire from the spark plug to see if it was dirty.
Everything looked good. Two days later my car started missing. I
figured I broke a spark plug wire so I bought four new spark plugs and
wires and replace the old. While replacing the spark plugs I notice
oil was on my spark plugs and some oil on the wires. I am not buring
oil. My car is missing when I first give it gas and then it smooths
out. That happens in every gear. 1 through 5 can some help me out

 

what mileage?

oil on the plug lead is because a seal is leaking. cheap to replace and
not the cause of the misfire.

first, check for ecu codes. if nothing, check the distributor cap &
rotor arm. other than that, the "misfire like" symptoms list is long &
includes things like egr valve, thermostat, injectors fouling, pcv
valve, etc. try the first two listed then report back.

 

The milage on the car is 147,000. I was reading my honda automotive
repair manual. It said check the gapping of my spark plugs. I
compared the old spark plugs to the ones I put in today. The plug gap
is suppose to be 1.1 mm. The plugs I bought today are about .5mm
Bosch platinum could that be causing it to misfire. I already took
out the new ones and compared them to the old ones. I know if I left
them in there a while my engine would get really hot. It was already
getting hot earlier that is when I started reading about the gap of
the spark plug

 

What seal was you talking about that could be leaking. After I took
the new plugs out there was no oil on them this time. Everything
looked good but if it is a cheap and easy fix I would do that also

 

i wouldnt recommend bosch plugs. they're not OEM Honda plugs. you should
look for NGK or Denso plugs for your Civic. There is a difference. and make
sure your plug wires are a minimum of 8mm thick not the cheapo 7mm ones.
that definetly is important.

seals are a cheap easy fix. most auto repair places stock them because
they are a common failure.

regarding plugs, my experience with bosch is not good. one day they
work, the next, the car's deader than dead. as others say, stick with
denso or ngk. even the cheap plugs are better than bosch. it's not
like the civic has an access problem requiring the use of long life
plugs. i have iridiums in mine, but that's because i'm a geek.

 

I have had Champions short under load - I don't recommend them either.

yes, for these compact, high temp plugs, champions don't do too well,
but on the older style exposed plugs, champion were great in my
experience. never had a set flunk on me, unlike bosch which let me down
consistently.

 

I haven't tried any of the newer ones. I had one fail in my Lotus (Renault
engine) and in a Ford Maverick, both in the mid-70s. I haven't bought any
since. Each time they worked okay below maybe half throttle.

This is coopdog696 and I found the problems with my 1991 honda civic
dx. Well I actually took it to a repair shop. The guy who runs the
place ownes the same car and it is a street runner. Any for all you
to know while my car was puttering and not running properly was the
inginition coil was messed up. It is a very common error with these
cars. It only cost me $150 dollars. Thanks everyone
