my high maintenance girlfriend....stalling again

[worangejuice]

1992 ka24de
new alternator,starter,spark plugs
140,000

Just replaced the aforementioned in the last two months myself,and now my check engine light went back on after I filled up my tank.
checked my ecu.
codes:
EGR malfunction
Fuel injection leak

did the fsm trouble shooting pull each injector connector and each one sputtered. egr is lifting and not sticking,engine sputters when I physically lift it myself. No visible injector leak w/o taking off. All the lines/hoses are connected. getting spark from my plugs.

Car will stall out when on a full tank or ran for a long period of time. Also when I push it to 'bout 5-6k rpm's. Then when I come to a stop it will die , or idle will fluctuate greatly.

Car has been running good latley, since I'm driving it like an old lady:faint:

Only things I think are left are the distributor cap (never replaced myself,yet)
Or the MAFS.

Only thing is the codes I got do not pertain to these two, or is it a cause and effect

I'm thinking it's something in the fuel system, or a cracked hose I can't see. What would a good test be to find a leak in a hose. I've heard of the soapy water thing, will that administer good results?

Just need other testing procedures that I may have missed. Like I said everything looks good and 'tests' right.

Sorry for the long post, just being thorough.
Thanks

egr probablt stuck open by carbon

I'd check the fuel pressure, and rev the motor while monitoring it to ensure it's rising to as high as it should, that will let you know if your fuel pump is dying off or not.

I suppose you could try a different MAF or clean the hot-wire, but it really sounds like a fuel pump or fuel filter. Buy a z32 fuel filter, its an upgrade anyways, to ensure you get good readings. Get back to us with that.

and as for the EGR, make a block-off plate...It's too much of a pain in the ass to replace if it's bad, and either way you will get those 1-2 ricer ponies as well. :X

I already have the Z32 filter. I'll check the fuel items tonight.thanks

seafoam that bitch get all the crap out of your egr

[worangejuice]

haha ^^ A fan of the seafoam! Last time I did that was in spetember of last year. I've done it twice within two years. I don't think it should be more than that. It does work hella good though!

[worangejuice]

some other forums were talking of loosening the aac and tinkering with the whole throttlebody intake linkage. pretty much the whole air/fueul passenger side of the engine is what I'm thinking. Hopefully it's just the fuel fiter(haven't replaced it in a while) Will look up the fsm fuel pump removal/test at home tonight. ( i just drank cofffeee)
