Need Serious Help - Car driving me crazy

[sephir_07]

today i tore down the top end again and found hairline fractures in the spark plugs.
so im getting more friday. ill let you know how it goes man
maby ill remove the hood and drive around like that when i get new plugs. this would let us know if its the leak messing with our sensors.
let me know what you come up with.

and yes as soon as i get to 2000 rpm trouble sets in... then beyond 3000 its great!
maby we have faulty coil packs?

I was suspecting spark plug issues as well. Maybe a valve cover gasket leak drowning them in oil. I have hte plugs, just have not checked the old ones or made the switch as of yet.

I should also be replacing my down pipe in the near future so that should help answer the emissions questions too.

I have a very similer problem going on with my 87 supra turbo, i found out after replacing spark plugs fuel regulator .... that i had a plugged strainer on the fuel pump in the fuel tank and plugged fuel filter which restrict fuel pressure due to the rust in the fuel tank. The fuel pump was working extra hard to pump through the rusty strainer. There is a drain plug in the center of your fuel tank try to empty some of the gas in your tank and see if it comes out clean or not.
Iam curious to know if your car has the same problem as my car did. Good luck.
