upper intake manifold..



it works on piston engines also...

I'd just be a little worried about vapor lock on a piston engine. I've never done it on a piston so I can't really say, just speculation.

vapor lock has to do with a fuel issue , not water ingestion

ROTARYROCKET7 05-15-2005 04:38 PM

well good thing u got that turbo II motor/tranny



Now u have this motor to take apart and play with

THat would be "Hydro Lock".

BoneT2&Harmony 05-15-2005 07:57 PM

Sounds like your plugs. Change em. Change the wires while you're at it too.



And you don't need some kind of special socket to remove the spark plugs, use an adjustable wrench/imagination.

G2G 05-15-2005 09:48 PM

errr, yeah I'm not exactly thinking. Hydro lock not vapor. Regardless, it sounds like it is not a problem with a piston, so disregard my previous statement.

for a problem like your having, start with the basics. Verify you have no major vacuum leaks, the AFM is plugged in, ECT is plugged in, you have spark on a 4 plugs. Check the color of the plugs, etc.

Honestly, doing the "steam" trick isnt going to do **** if the motor is running as bad as you describe. Don't waste your time doing that and spend some time troubleshooting the actual problem!

i am willing to bet its the plugs and wires. i had the same exact problem not too long ago, it was backfiring like all hell, the power would come on and off jerkin the whole car around and ****. i for sure thought i popped the bitch but actually it turned out to be old plug wires. it also felt like it was runnin on one rotor cause it was. the rear rotor leading plug wire was arcing off the wire boot straight to the block!! i could see the huge arc in broad day light.
