Wisemen, help?

[trapspeed]

I've posted this problem two other times now and it hasn't been responded to so I'll try this again, this time with a reference to the wisemen to hopefully catch their attention.

Just recently I used a product called "Seafoam" which is a carb cleaner. I poured half a bottle into my crankcase and the remainded went into the intake manifold via vacuum tube. Afterward, I switched out the sparkplugs (gapped them to around .028, not too sure because I have a crappy gapper) and got my oil changed the other day.

However, when I get on the gas the motor bogs in hesitation. The bogging is very short and fast in repitition. The car does not want to go WOT at all. Shortly after I attempt to put it in heavy acceleration I get an extremely loud pop out of the back of the exhaust which is then followed by a cloud of smoke, sort of whitish/bluish in color. It has a strange smell to it, also.

I don't know whether or not it's my sparkplugs causing the problem or not. I really need help, though. Thanks.

How much have you driven since you used the stuff?

BTW, it's really never a good idea to post the same question more than once.

You do know that carb cleaner is not for fuel injected cars right? Most will leave a residue of oil behind and some will kill oxgyen sensors which is what I suspect you may have done. If you have a datalogger, AFC, or voltmeter check the O2 signal and see if it cycles rapidly once the the car is up to operating temperature. If it doesn't cycle it may be dead.

Next take $5 and get a real plug gapper and you might as well pop ~$10 for a set of NGK's while your at it.

After that I would look to see if I didn't forget to hook up a vacuum hose or if I have a big leak (read loose) in the intercooler system...

Good luck

if you put any of it directly into the oil you need to drop your oil pan and clean the screen off cause there is going to be a bunch of crap on there from all the stuff its cleaning. I used seafoam and just used a vacuum line to suck in the liquid and poured a little into the gas tank.. worked fine for me.

I appreciate the quick responses. I will do what you recommended and see if I still encounter the problem. I used the same stuff mentioned in the following thread : http://www.dsmtuners.com/forums/showthread.php?t=123649 . Noone else seemed to share the same problem I had.

I read the first couple of posts on the link you put up but it is a 5 page thread so I'm not sure which method you used.

If the stuff is the same a most combustion chamber cleaners then the process should have been something like this.

Crank up engine, let it come to operating temperature and then start spraying the stuff in to the intake as close to the throttle body as possible. Preferably just before it so it will clean the Idle air control path and the throttle plate. The idle should be kept as low as possible making sure not to stall the car out. After 30-60 seconds of spraying, open the throttle plate some more in order to clear out some of the cleaner. This will prevent serious ponding in the intake system and keep it from locking up. Continue these steps until you stat to run out. Once the can/solution starts to run low, let off the gas and let the engine start to collect the last bit of the cleaner. As soon as you run out of the cleaner, shut the engine off.

One of the largest contributors to intake system gunk build-up is the PCV system fumes staying in the intake as it cools down. These gases solidify and collect on the intake walls. So... the cleaner you just put in will do much the same thing so long as you did not raise the RPMs as you were emptying the can. Let the cleaner collect on the walls and soak in.

Let the engine cool down probably 30 mins or so and crank the car up. Getting it running may be difficult but try not to cycle the key too many times. On fuel injected cars every time you cycle the key on, the injectors spray. So you don't want to flood the engine. Once it's running, drive the piss out of it to allow the carbon to break free.

There is also another way of doing this which involves warming up the engine, pulling all four plugs and spraying the cleaner down in to the cylinders and letting it soak overnight. In the morning you suck out as much as you can and drive the piss out of it again. This manor requires changing the oil after your drive because you don't want that cleaner in the engine oil.

Note you may fould out your plugs and be prepared to replace them after this service.

Things I was wondering about here...
"Just recently I used a product called "Seafoam" which is a carb cleaner. I poured half a bottle into my crankcase and the remainded went into the intake manifold via vacuum tube. Afterward, I switched out the sparkplugs (gapped them to around .028, not too sure because I have a crappy gapper) and got my oil changed the other day."

You said the crankcase... now to the professional mechanic that means in the area that the oil goes and NOT in the combustion chamber via the intake system. So which was it? Crankcase or intake?

Also, "Carb Cleaner" has kind of become a generic term for anything that we spray in to the intake system to clean it or get the car started. I use the term Carb Cleaner but the can actually says "throttle body cleaner" so that may simply be a terminology hang-up again.

From the time you started this cleaning service until the time the problems started, how far have you driven the car? How far have you driven the car while the problem is acting up?

Finally, if you have a problem that needs more assistance than you are getting, PM a wiseman or moderator for help. There's no reason why anyone should have to post three different threads before you get help. Just PM someone if you don't get help within a day or two. Thanks,
Doug

Good god, pop the three bucks for a real gapper and set them right before doing anything else.
