Re: Ticking / misfire /check engine light.

Update: Going to need a new motor. no compression in cylinder 2 and some lower end knock.
would it be safe to drive at least 30 minutes at 45mph to a shop i know of that could install the new motor for me?
also any recommendations for companies to go with for reman motors?

Re: Ticking / misfire /check engine light.

Why exactly would a fuel injector that "isn't doing anything" 'soak' the cylinder and wash away your compression?

Re: Ticking / misfire /check engine light.

Idk. Both mechanics say I have no compression in cyl 2. (Motor only has 140k on it) First mechanic originally said oh itís just the ECU. But then upon further inspection he noticed the compression being gone also.. and then spark plug soaked, and scorched cyl walls. So he said the ecu most likely told the injector to spray constantly? Iím not entirely sure of anything anymore, Except that I have no compression.

Re: Ticking / misfire /check engine light.

I would still investigate where the compression is going? Out the valves? Through the rings? A leak down test will give you more information. If its cartooned up valves, sea form, the Mopar or other brand equivalents of intake/valve cleaners, etc. may do the trick. What exactly is the lower end knock?

If the injector was flooding that cylinder that makes sense, but that would be the opposite of "doing nothing".

Re: Ticking / misfire /check engine light.

yeah, so I think the ecu could have told the injector to flood it.
but now that there is no compression in that cylinder, when i disconnect the injector wire it doesn't even make a difference in the idle/misfire, because of compression being gone already. its not that the injector is doing nothing, its just that it doesnt effect the idle/ misfire anymore. i hope that makes sense.

I found a motor for $1500, and i found a guy to help me install it. he quoted me $700. so all in all under 3k isnt that bad
