Ok so I have a 1995 s14 auto.

Story
Me and my girl went out car drove fine and returned to my car 2 hours later started right up drove 2 blocks and bam.
Cars acts like dying
Sputters
Bogs
Gas pedal to the ground but takes 5-10 seconds till it actually accelerates
Died at a light twice
I checked the battery was fine
Pulled the negative on the battery stayed on
Pulled the injectors they're fine
Fuel pump purges and works
Car can idle all day at my house but can't run properly

Anyone help me out with this it's an emergency it's my dd and my project isn't up and running.

Changed my wires 3 days ago.

Sparks plugs 2 months ago so it can't be those.

I don't think it's the gapping because I changed the sparks 2 months ago with no issues.

Pop the ECU out of the passenger side kick panel under the dash area and you can look up some instructions how to check the ECU codes yourself, and it should tell you what is up.

flipmike22 · 01-01-2013, 02:53 AM

So I got codes 33, 34 and 14. I unplugged the knock and the o2. No progress.....anyone help?

Vacumme leak. Check the egr hoses in the back probably a ripped hose.

I looked for vacuum leaks breifly I didn't hear or see any but ill look again. Also ill check the egr. Any other suggestions?

mantas · 01-02-2013, 10:05 PM

What about compression test? If you can give it a shot always remember to have throttle plate held open and dont dump fuel so disconnect the pump or pull the fuse. To find a vacuum leak use some brake cleaner or carb cleaner and spray a little on suspect hoses or seals but have a fire extinguisher handy lol. Some people say soapy water works but i have never used it. Supposed to bubble when sprayed. What do the codes mean did you look into it? Bad o2 would just make it run super rich since the ecu would dump more fuel and may cause bogging but usually car still runs pretty good. I had mine unplugged for a long time didnt notice it until someone said i was running really rich.

Just looked up the codes all lead to bad maf. I got a spare ka24de if you need one. Unplug maf and see if idle improves or if car dies. Also could be bad TPS mine would cut out at WOT because of a bad TPS. Should read 2.5 or 3.5 volts fully open and .05 closed if i recall correctly.

mantas · 01-03-2013, 01:59 PM

So did you figure itput?

mantas · 01-05-2013, 10:18 AM
