i own a 87 iron duke fiero I got beach sand in my filter and maybe in engine it got past the filter idk how. car drove fine but had loss of power found out ignition wires were loose plugged back in. white smoke comes out now. it hesistates when I give gas about a sec then runs good. throttle sticks I put wd40 in the throttle cable but still gets stuck any ideas what to do? I know its the sand but I don't know if maybe I got sand in valves and it will go away or the engine is crap it drove aswsome last 3 years no problem idk milage

Put some marvel oil in the oil fill run the engine to operating temp and then drain the oil and change the oil filter then do this again. You may not be able to save it though.

White smoke usually means water or coolant is getting burned, it is the coolant level low?

So, there was sand in /around the TBI (not carb)?

There can be sand and junk on the outside of the filter, but the housing.

sand got in the intake ill try the marvel oil . I bought a head gasket and bolts if the oil don't work ill try a headgaasket .40 bucks for all the stuff I got a discount. I know im burning coolant but coolant is clean im going to drain oil when I try the marvel oil to check for water. im going to do a compression check also. I cant fine a tread or video for head gasket is there one? I replaced a head gasket on my 93 b2200 mazda pickup it was easy. Im sure I can do this one it looks similar

I have to ask... how exactly did sand get in there? Wrong or missing filter?

Also, there is an '87 manual online: http://dl.dropbox.com/u/807...Service%20Manual.pdf

Before throwing anything more parts, money or time at it do a compression check and see how much damage has been done.

Just a tiny bit of sand in the oil will quickly destroy cylinder walls, rings and bearings. I dont think it will do anything to make water get in the cylinder though...thats a different issue. You might flush the crankcase out and cross your fingers, but if you drove it home, you probably destroyed it.
