Car is trembling like it wants to turn off.

I recently replaced my intake manifold for my 2000 Mustang GT and my motor is trembling and shaking like it wants to shutoff... It doesn't do it all the time and at high speeds I have zero problems.
Anyone know what this could be?

Did you check to make sure there weren't any vacuum leaks? Sounds like a vacuum leak to me.

I'll check that out... A friend just told me to disconnect the battery and re tune and that should stop the problem.

Sounds like a misfire to me. Check all your coils and make sure they are firing. At higher rpms you wont notice a misfire

Re: Car is trembling like it wants to turn off.

Did you drain the coolant before you swapped the manifolds out? Its pretty common to get a bit of coolant in one or more of the sparkplug holes. Most commonly it is plugs number 4 and 8. Try pulling them and cleaning them off.

Re: Car is trembling like it wants to turn off.

sounds to me like a missfire as well, clean the maf and IAC as well regardless as it probably needs it

I did not drain the coolant and a I removed the manifold, coolant fell everywhere.
Haha so I'll take out the spark plugs and clean them off.
What's the IAC?
what would cause a misfire?

IAC is your idle air control valve. It is on the front of your throttle body with a vacuum line running into it. Ya cant miss it. Just pull it off and spray the crap out of it with throttle body cleaner, then let the excess run off before you reinstall it. Also be careful with the gasket for the IAC,it is paper and tends to be brittle.

A missfire is caused when the sparkplug isnt firing at the right time or not firing at all. If you get coolant in the plug holes it causes a missfire because your coils have to send the spark through the wires and the coolant to fire the plug. This causes either a weak spark or no spark at thus causing the missfire.

Ok, that sounds like exactly the problem that is going on with my car. I'm pretty sure my spark plugs are wet and there could be a vacuum leak. I'm gonna mess around with it today and I'll let you all know if I solve the problem
Thanks for the help!

Try not to get coolant into you cylinders. It takes a minute for everything to blow out.

Read the trouble codes with my turner and it says Misfire detected in Cylinder 4.
I've been running the car for a week with it bogging like this and no serious things have occurred. Bought a new set of Motorcraft spark plugs and I'm gonna replace all of them and reapply my diablo tune and let you all know how it runs (:

When I installed my PI manifold I got the same code. Pulled the plug and wiped it clean and cleaned the wire boot. Haven't had the problem since.

Yeah it bogged real bad,but if you haven't changed them in 11 years it would be a good idea to get a fresh set in. Should probably change you wires also.

Yoi should put dielectric grease on all electrical connections amd spark plug boots as well. Better current and helps alot for corrosion and wster shorting things out
