Default Cylinder Misfire

While changing my thermostat in my 01 recently, I somehow managed to break the "Tube Fuel Supply" right at the fitting for the fuel rail.

I replaced the broken line and now my PT is running like crap! I am sorta mechanically inclined and am definitely a DIY type of guy, so I am willing to get dirty and try to fix it.

I don't know if maybe there is air in the fuel system now??? If that is even possible. I've seen a couple resolutions online about cleaning the injectors and blah blah, but I'm not sure that's it. It worked before I fixed it. Is there a fuel line bleeder somewhere?

Yes. At the end of the fuel line on your 2001 there's a valve that you can measure fuel pressure and get rid of any excess air.



If you have a guage, you should see somewhere between 53 to 63 psi.

bleeder wont fix that. air bleeds itself out. check all the fuel line connections you touched, check all connectors you touched, check the upper to lower intake gasket area for leaks with starting fluid, check the plugs on the injectors to make sure they're fully seated. if you had the upper intake off, makes sure you didnt mix up the two plugs on the back of the intake that are exactly the same. it's something easy/dumb like that, not air in the line though.

I am gonna check the connections when I get home from work. I didn't take the whole intake off. But it could be a plug or two. But thank you for letting me know it is NOT air in the system.

Actually, I didn't think of that, but it could be the manifold gasket.

Edit: I did take the bolts off the upper intake to get to the coolant hose. So I'm betting it's the gasket. Dang. I didn't want to spend any more $$$

I fixed it. It ended up being the first plug on the fuel rail. It was, indeed, unplugged. But I did replace the intake gasket just because I had the part. Thank you all for your replies and advice.

COOL...glad you found the problem Puke. But I have to say, this line from your first post made me laugh my butt off. Mostly because I seem to have a LOT of stuff work...beFORE I "fixed" it. ;~)


Glad the problems gone brother.
