Clean Carbon from FI engine
 

I've been seeing posts on cleaning carbon from carborated engines. How
would I do the same thing on a MPI engine? Pour water in where the air
filter hooks onto?

thanks,

bill

Yes or find a vacuum line to suck the fluid in.

Just keep using a major gasoline and your chambers and spark plugs
will never carbon foul, and your injectors will stay clean.

Re: Clean Carbon from FI engine
 

Well, I believe my jeep was running really rich before I put the FI on. A
couple of reasons I believe this. First, I couldn't get rid of the stinky
smell even after I put a new O2 sensor in. Then, when I removed the exhaust
manifold to put a new gasket on I noticed the previous owner or his mechanic
didn't use all the bolts to tighten the manifold down. I know this because
the manifold would not line up to the bolt holes on the head. I had to
grind out the end bolt holes amoung others to get it to fit properly. So I
suspect it wasn't on there very well and so the O2 sensor couldn't
compensate properly.

Now it's on there correctly, nice and snug but I'm afraid it has accumulated
bunches of carbon.

Previously I mentioned I wasn't hearing any pinging from the engine since I
put the MPI kit on. That has changed. Before I didn't have the distributor
seated correctly because I didn't have an indexing pin. I since got one and
seated it correctly and although it's running much better I'm now getting
ping. I up'd the Octane to no avail so I'm going to JeepsRUs who told me
they can advance the timing to get rid of the ping.

I was thinking that accumulated carbon may also be a cause of it pinging.
I'm going down there today to see what can be done.

thanks,

bill

For lack of a better description, at the throttle body. Aka
the thingie that has a movable plate in it that looks like
what would have been a throttle plate in an older car.

A squirt gun or spray bottle works ok, some folks put a bit
of alcohol in the water, but nowhere near enough to actually
burn.

Could you be too far in advance. I've heard ping when my motor is too far
advanced.
