cars stalls out !!!!!!!!!!!!!!!!!!! - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

lilaznjeff · 09-28-2003, 06:31 PM

i just finish the sr20det swap and
check all the wires, harness and piping
when i start the car the car will idle so bad i will almost cut out
so i was wondering could it be my maf or something else
i thought it was vac leak at first but i check all the piping and it was a tight and seal,
i have people told me that i could be the maf, inganition timing, cam angle sensor,
but the most unusal thing is
when i unplug the maf the car will idle fine
please reply guys
thanks

lilaznjeff · 09-28-2003, 06:33 PM

and also i was wondering what is the differnt of looks performance of the 89-90 maf 91-93 maf and sr20det maf
is all the samelooking

Clean the mafs sensor unit carefully with a q tip and alcohol. Gentle!\
\\

Do not disrupt the wires.

Very careful on the windings.

And... clean the connectors...check the grounds...you can readjust the idle...it is fine to turn it up to proper..all this just don't fall in place with our gas and environment...also the engine has not been run out in a while.

Do some Italian tune ups and get it leaned out and change the oil again, pamper, and reset ecu a few times. It will click in there.

Leaks in pipes...check many times.

One dude had a bad intercooler...causing problems.

Run a can of techron to clean the injectors. Take a pencil eraser to the terminals of the igniter terminals and make sure it is clean. Make sure ECU is fully plugged in and instrument cluster is grounded properly.

All this schnitt. Fuel filter??? New. Bigger Fuel pump? Needed.

EGR, look at leakage.

Go for yourself her.

Hope some of this helps...and check all vac lines. no stone unturned.

Does the car idle okay after it has warmed up?

lilaznjeff · 09-29-2003, 09:37 AM

same thing
the idle will just be hella low and it will died out

*sykikchimp* · 09-29-2003, 10:04 AM

has your ECU thrown any codes?

lilaznjeff · 10-01-2003, 06:14 PM

nope
it gave me a code for 55 that means its runing fine i guess

einherjar · 10-02-2003, 06:15 PM

bov, do you have one if so what type, make sure all the turbo tubes are plugged in and in the right spot.

rednerd · 10-03-2003, 08:10 AM

Have you tried adjusting the idle air controll motor? There is an adjustment screw that you can see if you look between the #2 and #3 intake runners. Turn it out to raise your idle...

lilaznjeff · 10-04-2003, 12:52 AM

i try adjusting the idle but then
it will sound like its at 1500rpm
sorry my gauge cluster dont work

einherjar · 10-04-2003, 09:45 AM

agin check BOV see if it is blowing out air at idle, also, fuel lines.
fuel rail!!!
when they pulled my SR in japan they did it by the rail and because it wasn't sealing properly it wouldn't idle, i actually removed it and bent it back.

to check if it is fuel related, if your car is ideling like shit or barely idleing if you need to hold the key down or whatever, give her 1/2 throttle and hold it for a few seconds, if it is fuel related she will eventually kick in, it will sound like it is idleing fine, but once you let go she will die.
if so ... check fuel issues.

lilaznjeff · 10-05-2003, 12:31 AM

i dont think is the fuel rail cause my car is running pretty rich
cause when i unplug the maf and drive it
i smell alot of unburn fuel if thats the case
i also try swapping ecu it will still do that so
i like 60 percent sure that is the maf
but i been thought like three of them aready

also i try using the 89 sohc maf
i will still do the same
i was wondering will it work with the sr
same wiring right
the harness is alittle different
so guys give me advice please
thanks

einherjar · 10-05-2003, 08:26 AM

the 89/90 mafs does work.

did you do the wiring right on the mafs?
and do you have a bov that is blowing air it idle?

lilaznjeff · 10-05-2003, 07:29 PM

i used the one that came with the front clip
and i took it apart to take a look at it
i think it works fine
but im planing to change it any ways

lilaznjeff · 10-07-2003, 06:52 PM

even with the new maf
the car still dies out
alot of people told me about bov
but it seems like is the intercooler
please help me out!!!!!!!!!

einherjar · 10-07-2003, 09:42 PM

could be the intercooler, try running any pipe around where the i/c would be, even PV would be fine but only let it idle for a few seconds.

speeddreamz · 10-07-2003, 09:57 PM

Its his intercooler...jeff...dumbass heh..how u gonna be faster than me with this ****...get a fmic like wilson. (i know him btw) Just incase u posted it since last time i told u it was the intercooler... n/m

lilaznjeff · 10-08-2003, 01:21 AM

also on the turbo extension i have a hole right there
it connects to the down pipe
i was wonder what kind of screw do i need to use to cover that hole
that hole is like a 17 i think
it use to be a metal pipe that connects to the o2 i think

speeddreamz · 10-08-2003, 01:24 AM

put the pipe back in, bend it fold it over acouple of times and seal it with gasket sealer just to be sure =D

lilaznjeff · 10-14-2003, 03:51 AM

i replace the intercooler another side mount
and the car runs alittle better but it will still stalls out some times
it can still be the maf right
also i was wonder i have a koyo raditator and i have nothing for coolant retain and it starts blowning hella smokes and i was wondering what can i use to hold the coolant retain
