ok, i replaced my timing belt on the weekend after it shredded on friday.
the thing is.. i am 99.9% sure the timing is right, i checked and double
checked and lined everything up twice......
but here's what's happening now; the fuel mileage sucks, and my turbo is
spooling up-- well, really nicely. :) too bad though that it is spooling
up so much that with not even 1" of travel on the accelerator the turbo has
no issues with trying to boost over 14.5 psi.
so then the computer kills the spark and fuel and i end up with this
surge-pulse-stall-go thing that is really embarrassing in noontime traffic.
any ideas out there what could be the cause? i didn't think that if the
timing is out or off by a cog somewhere that it would do this, as the damn
thing runs just fine. idles fine, accelerates fine, no backfiring, no dead
spots in the power band, no detonation, no black smoke out the exhaust.. it
seems to be an over zealous turbo and injectors on steroids.
is it the crank sproket being out one cog?
You either left the vacuum hose off of the turbo wastegate or broke the
vacuum hoses at the back of the valve cover, I don't see the make or model
in this thread but if it has the quad solenoid on the right side fender,
make sure you didn't knock off the vacuum hose at that. If you keep driving
the vehicle in an over boost state you could blow the head gasket.
thank you. i checked the vacuum line to the actuator.. that's fine.
nothing else appears to be broken, or cracked, or anything. :s i can't hear
any vacuum leaks, nothing is leaking from the bottom besides the usual
amount of oil from a 2.2L.
the thing is that i didn't go behind or on the right side of the engine at
all, during the repair. the car stalled, so i coasted into a parking lot
and tried to start it. the sound of "not enough parts turning" was all i
needed to determine that it was the timing belt, i knew it was in bad shape
to begin with.
so i took off the AC compressor, which is seized up anyway.. i lowered the
alternator and took off the belt, i lowered the power steering pump and took
off that belt. i then removed the tire, and then removed the crank pulley.
then i took off the timing belt covers, and the old the belt just fell out.
i cleaned up all the sprockets, aligned them, and slipped the new belt on
and set the tensioner. i put the crank pulley back on and hooked up the
water pump and alternator, ... then she fired right up when i turned the
key. so i put the timing belt covers back on, power steering pump belt, put
the AC compressor back in place at least so i don't have to undo the
lines..... i touched absolutely nothing else :\
think i busted somethig else in the process? :( that's gonna suck if i
did. i will go have another look, this time i will jack up the car and have
a look closer behind the intake manifold. it's a manufactured in '87, model
year '88 new yorker turbo 2.2L. it has the bigger intake manifold that
prevents me from seeing anything that might be behind it. :(
...wait.. in retrospect.. what if i had the crank aligned TDC not on the
compression stroke? no.. i don't think it would work very well if i
Once again. check the hoses, there is gonna be one off or broken, the one to
look for is underneath the turbo, use your emission label on under the hood
to trace where they are and where they go, take the one off the turbo and
locate where it goes, put your finger on one end and blow thru the other, I
bet you can blow thru it cause it is broken at the main tee behind the valve
wow, thank you so much =))) i dunno how it happened, but one of those lil
plastic ones had come out of the end of the rubber adapter to go to a bigger
hose. when i jacked the car up and crawled under, finally, i saw the bigger
hose with the rubber thing hanging down. plugged that sucker back in, and
away she goes.
thanks again! =)
