please help :s

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 didn't.. nm

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 cover

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! =)
