Newbie engine problems??

[OklahomaS14]

My car is a 95 240sx. It's a KA pretty much stock except an intake. It has about 130,000 miles. Up until now it hasnt had any problems. One day I was driving home and it started running really bad died a couple times and now will not start..I have checked everything i can think of like:Fuel PumpFuel FilterAll fuel Lines(gas is going through to the injectors)It has a 6month old dist. cap, rotor, plugs, and wiresI also checked all fusesI have checked all conectors I could see.

The day before it did all this all I did was put a new batt. on it.

One other thing, sometimes I could get it to start(once after I checked and reset the ECU, which said the Front O2 circuit was bad) but it would idle really good and I was able to rev it up slowly all the way to the red line, but if it was a sudden tap of the gas it would almost die. Then after maybe 10 minutes idling it started to run bad and died without even pushing the gas.

So is there any suggestions, maybe something I am missing??? PLease help me, cuase I reallly miss my car already..

try the wiggle test. get her running and wiggle the maf, ect, dist, and other wiring to see if it messes up. try pulling the plugs and checking them right after it stalls out. watch fuel pressure as she runs and dies. try messing with the ign timing too. the comment about the car only revving up if you slowly give it gas sounds like a jumped timing chain. may want to pull the valve cover and verify the marks line up at tdc.

ok well the car wont start anymore. It turns over but wont start..I was going to change the ignition timing a few minutes ago but the batt went dead so I gave up for the night. But I did do the wiggle test to try to get it to start but nothing has worked so far.. thanks for the help.. if you think of anything else let me know
