My Car Is Giving Me The Shits!

[taiphan]

Ok.. don't get me wrong..

i love my car..33 S2

it's bautiful..lower..full Nismo factory kit not one of those aftermarket weird looking one with more wave / curve than a fat lady on steroid if there is such a thing.

Just nice and plain and muscline not all done up like a metrosexual...

but the engine is giving me the shit..

some day it just run like a dream.. gear easy to change.. purr like a little kitten.. and full of grunt..

however someday it shit itself and runs like a truck.. exhaust is really loud (even after the silencer is fully closed).. no power.. impossible to change gear..

what could be the problem?

- coil?

- bad fuel? (only use BP or Shell top of the shell stuff)

- engine going?

- fuel pump?

- i have mental problems and imagining things..?

anyone experienced similar issue?

any comments is appreciated..

back to work now..

Ill start with the obvious?

AFM? Check soldering inside it. If not, resolder it. Might pay to swap over with another AFM.

if your pod is insecure, secure it asap.

Coils? Check to see if they are clean inside.
