Ka24de sputters and dies when warm

[steveff]

So my S13 Ka24de keeps dying on me. It's giving me symptoms of a bad TPS where I'll step on the pedal and it'll sputter like I'm blipping the gas pedal. Or ill press the pedal and it won't do anything. Sometimes it will stutter almost like a fuel cut? It'll then bog and stall.

It only does this when the engine warms up to operating temp. It doesn't over heat or anything. The temperature gauge reads the same temp the entire time. But when the engine is cold, it doesn't give me this issue.

I replaced the TPS and I'm still having issues.

So I thought it was bad gas, ran it to empty and filled it with some 98 octane I was able to find.

Still dying on me after about 10 minutes of driving, although today I started it up after it died and it acted like nothing happened.

Walbro 255lph fuel pump comes in today, to eliminate the possibility of a bad pump.

And it died again... pulled the plug on cylinder #4 and there was no change in idle.

Dead plug or clogged/sticky injector maybe?

You should be telling us what the problem is, but you just ran back to the thread you started with more questions. This is not a blog or diary. You could have tested spark and fuel instead. You have to do both because it could be both. Or neither!

Remove the spark plug, Check for spark. You also should check the wire, if there's no spark. Then check the injector.

Then you can tell us, if there is no spark or no fuel. Or if you have both.
