i finally have the cam timing correct, now there are a few other problems. it fires up only when i have it jumped to another car. maybe once or twice after the cables are off.battery, might be bad but it is fairly new 6 mounths or so. i'm thinking the alternator might be bad now.when it does start it revs to like 1500 pretty smooth then drops off quickly sputters and stalls. it runs forever at high rpm's if i stay on the gas.could a bad alternator make it idle like this?it has good spark, timing is close, makes 34 psi fuel pressure, and 179-182 compression on all 4 cylenders. i've removed the whole egr system + wired in resistors so it doesn't throw any codes. anyone have any ideas. it's so close but i can't seem to get over this idle thing. thanks~peace

sounds like you have a hurrendous vaccum leak. check pcv and brake booster hoses make sure they are connected.

everything looks to be sealed up good. i tried to test my alternator today but now the car won't start at all, even when jumped to another car. it read 13. something while being jumped, i then tried to start it while looking at the volt tester and i hear a rapid click and the volts drop to 7 ish

o, another reason i question the alt, is b/c when putting everything back togeather after the head rebuild i put the intake manifold gaskit on backwords. so the main radiator hose wasn't sealed to the head and poured radiator fluid all over the alt. can that screw it up? thaks for the help thus far i'm really excited to get back on 4 wheels. rainy season is upon us floridians and i cath it everyday on my bike.

As I said this sounds like its got a huge vaccum leak. especially if you can get it to higher rpms and it will stay running. You said you put the intake gasket on backwards?? did you correct that?

get a volt meter on your MAF and watch its voltage when you start it and as it dies down, try to maintain a higher rpm and slowly release the throttle while watching the meter. see how low the voltage drops to at the lowest point it will still run. post your results.

If the voltage drops below the standard idle voltage between 1.3 and 1.5 volts It indicates air is getting in somewhere else but the meter doesnt know it and slowly cuts the fuel off.

cool, i'll try tomorrow, thanksmy only concern is for it not to run this has to be a pretty big leak, right? could it have something to do with all these hoses i have plugged from the egr.

have you checked the connections on your battery? if you've got a corroded ground or bad connection on the positive it could cause alot of erratic behavior like this too. I didn't see if you'd checked the status of your battery terminals or not.

good luck!

Is the egr valve even installed on the manifold?

No I was reffering to the egr valve itself, big gold flying saucer looking thing.

The one attached to the intake manifold is the one I am talking about? Is it still on the manifold?

nope, all gone. i did notice today that the fuel pressure is lower then it should be now that i've moved and plugged all the egr rubber hoses. i hope thats the only problem is these rubber hoses.should i just take it somewhere, if so where? i'd really like to get her going again.

If you removed the EGR from the intake manifold you now have a huge whole in the intake manifold.

That generally qualifies as "sounds like you have a hurrendous vaccum leak" [Quote from my first post.]

i'm confused yet again, sorry i'm retarded.where would there be a leak, the only exposed parts of the intake mani are all the metal tubes jetting out? i thought. the one furthest to the passenger side of the intake mani i have going to the FPR. the four on the motor side of the intake i now have plugged into each other with 2 short hoses. where is the whole. sorry again and thank you so much for all your help
