Lots of smoke and no go ???

Postby schooner on Mon Mar 26, 2018 12:16 pm

Hi gents have an intermittent loss of power problem.

Was towing my boat home from fishing just cruising along all good.
came to a set of lights and gave car a bootfull to get it moving heaps of black smoke and stuttering did not accelerate much would not change up gear, backed of and eased it up to 100ks seemed ok. every time i put my foot down heavily black smoke very sluggish.
got home check inter cooler hoses and had a poke around under the bonnet could not see anything untoward.
Unhitched boat went for a drive and still suffered the same symptoms had another look still could not see anything obvious.
went for another drive all seemed OK again no smoke good acceleration ??????????

i have the electronic EGR bypass and a chipmydiesel box set on three.

just had service and had timing belt done and balance shaft belt replaced.
The car is still using a little bit of water which may be head gasket could this be the issue ????

Any advice appreciated thanks. Schooner

OK did some more test runs and only seems to do it in second gear once its out of second which it alarms over rev in but does not seem to go it takes off nicely.
checked map sensor line its clear should i still try clean out Map sensor it's self.

Will do MAF sensor when i have the cleaner.

Cheers

auto or manual???
mine is auto and does the same
but does it once when driving after a bit then dont do it again until next restart???
is really giving me the shits as the fuel pressure drops off the rail then i get black smoke out the back then after a few seconds it comes good only in 2nd gear as well

yeah mine is a auto.

also put some fuel cleaner through recently.
oh and put cable ties around the inter cooler hoses to stop a bit of expansion ?????
will do a check of all hoses this weekend.

if accelerating slowly does not do it runs well.

Likely fuel rail pressure limiter valve bugging out or restriction to air intake such as a snorkel tube sucking in?

If runs better with chip removed, I'd say limiter valve.

Ah OK no snorkel air intake seems OK.

Fuel rail pressure valve sound interesting is it hard to change or modify ??

thanks for the replies gents.

ok weeeeeeeelllll

not sure what happened buuuuut did a test run yesterday and no sign of problem ?????????

accelerated strongly with foot almost flat a little smoke but not heaps as before.

coincidence or not i don't know but the night before i fiddled with a couple of hose blew through MAP hose seemed ok and also filled my tank to full from half when i opened cap also noticed pressure escape from or into tank not sure.

but will see if it happens again with same results.

will report back in a week. Cheers

Wouldn't take much to block/restrict the MAP line.

You might have had the SCV stuck with some contamination.

Nice when everything goes as expected. :lol:

I find when I've run a few tanks without two stroke I sometimes get the dreaded 'stick SCV' syndrome.

If work is so terrific, why do they have to pay us to do it?

Thanks i reckon your right standard air intake system must be fuel pressure.

where do i get a modified one ??
