Car Cuts Out & When Stopping It Dies Completely

[dori34]

car is being weird atm guys.

sometimes it would just cut out when accelerating & when coming to a complete stop, it would die. id try to start it right away but it would just keep dying. if i give it some gas it would struggle to rev and just die as soon as i let go of the pedal.

if i leave it off for 5-10minutes then i can turn it on and it would be normal again.

when it first happened, i noticed my TPS was cracked cause of my strut brace hitting it, so i thought that was the issue so i changed the whole throttle body unit. but it still occurs.

i thought it was my fuel pump that was faulty so i bought a brand new walbro but it still happens.

any thoughts ??

when was your last service?

i'd be looking into the throttle/intake assembly, since you said it was originally due to that.

CAS?

AFM?

sounds to me that the TPS is dodgy or the wiring to it might be fried.....

[dori34]

last serviced less then 2000km ago

tried AFM

replaced TPS with new one as old one was cracked...

Long shot.. but reset ecu?

Have you had a geeze through the workshop manual?

[dori34]

checked the manual & no luck.

nothing in there about cutting out intermittently

tried resetting ecu & done ecu diagnostic test.

found one hose off the charcoal cannister that came apart but plugged back in and still happening intermittently

grr cars..

my CAS has a mitsubishi logo on it, is that meant to be?

yes all CAS on the RBs were produced by mitsu

How did you try the AFM?

[dori34]

i got one from a wrecker as i thought that was the problem initially..

i unplugged the afm plug, started the car & it idled sorta roughly and fluctuated so i guess it means the AFM is dirty..

strange this happens cause i tried it before and it worked fine..

anywho, im gonna clean the AFM.

any idea how to clean a rb20/25 afm??

do i rip the mesh off or something?

[dori34]

so no help at all??

any fries with that?

give the AAC a clean too - i'm sure you can figure that one out on your own

[dori34]

does woolies or petrol stations sell contact cleaner??

can i use metho or smething instead?

[342Four]

contact cleaner/carby cleaner is very similar

its just an organic solvent, usually containing some petroleum product, ethanol, methanol, ethyl acetate, acetone or isoproyl alchohol

dont use meth - it can 'melt' some plastics

if you have denatured alcohol that would work - or some original nail polish remover (non of this fancy non smell stuff as residues will remain behind)

whyte, i just spoon fed it to you - it cant hurt to go do a little of your own leg work can it?

give places like supercheap or repco a call.

[dori34]

Yes i know super cheap and repco have it but if you noticed i posted it late at night meaning they would be closed and only places open are woolies or petrol stations..

i ended up using degreaser, washed it & blow dry.

worked a treat.

update:

turned out to be the damn AFM.

the one i got from the wrecker to test it with was faulty as well thats why it didnt fix the problem.

what i did was opened up my afm, noticed the solder joints were sorta apart so i resoldered it back up & 3 days on without a single hiccup
