For a couple of days, my car would idle rough. Jumpy, above 1K rpm. Then finally, it started really rough, then died. I tried starting it up again, and it wouldn't start. The first time I tried giving it gas it would rev up, but after that attempt giving it throttle did nothing.
My friend and I took off the air filter, thinking it was clogged, but that wasn't the problem.

Here are the specs of my car:

S14
1998 KA24DE 76,000 miles
Megan Header
GReddy Air Filter

Any ideas of what the problem could be? My friend said to change out the fuel filter, so I'll try that tomorrow. I changed the oil around 450 miles ago, so it doesn't need an oil change.

I also have a timing chain problem, but it's the tensioner. You know, not the actual chain, I just need to get in there and spray WD-40 on the tensioner. At least I hope.

Any input is appreciated. Thanks.

 

Changing the fuel filter is a pretty good idea. Check the spark plugs, wires, & injectors.

 

also check the maf and for vacuum leaks sounds like a vacuum leak to me.
