Ive got a 1992 Nissan 300zx NA 5 speed. its got 128,xxx miles.

Here is one problem i was having...

When i stop somewhere for about 5 minutes (like to a gas station or something) and come out to the car and start it, it will start, and immediatly die. Then it wont start for a few minutes and i have to give it full throttle. Then when it finally does start, it runs perfect.

Here is the new problem...

When is start the car it idles normally for about 5 seconds then boggs down to about 300 rpms and dies after a few seconds. If i start the car and give it gas and hold it 3000 rpms after about 3 seconds the car will bog down to about 2100 rpms while still giving the same amount of throttle. The car runs like shit right now.

Ive changed the MAF because someone local told me to try that. I had an extra lying around so it was easy. Same problem still occurs.

I assume its a fuel problem. I havent checked fuel pressure yet or spark but i recently changed all 6 coils with known working ones.

Let me know if you have any ideas.

Thanks,

anyone??????

im having the same problem -_-. im going try and clean the throttle body to see if that helps because like you said its a throttle problem, so maybe it just somehow clogged.

i might have solved the problem, but im not entirely sure.

i cleaned the throttle body( i found a ton of gunk and residue in there) to clear up the intake passage to the engine.

i also tighten the throttle cable a slight bit

so far car is running good with no bogging

hopefully it will work for you
