Problems

Hey guys I'm new to this and this is my first post need guidance and advice.
I have an 03 3.8L and for a while now I've had bad hesitation and what feels like a skip but it's throwing no codes. Ive replaces plugs w/OEM motor craft platinums and replaced wires to Bosch. I've checked for vacuum leaks but nothing and even tho the lights off I plug my obd and get p0316 (crank sensor) so I replaces it and I disconnected my battery to reset computer and it ran better until I started driving more and all the problems came back. A mechanic told me it's recommended to replace the cam shaft synchronizer so I did and I was very careful to make sure if put the new one in exactly as the first one and I disconnected the battery again. Seemed like it was rerunning perfect then all my problems came back, I cleaned the egr also of a recommendation and still same thing. Also recently noticed it started back firing throughout the intake. Anyone else have these problems? Any help would be great thanks!

Coil pack my man, had the EXACT same problem, started by changing plugs, then crankshaft sensor, then wires, and finally changed the coil pack and the problem went away.

No problem! Does the ticking you mentioned on the other thread go away after the car's warmed up? If so it is a cracked exhaust manifold. Happens because the AC drips on the hot manifold which makes it crack, very common with 99-04 V6's, usually doesn't affect anything.

I do have a exhaust leak at the passenger side manifold would that make ticking noise? I found it when I was running sea foam through my intake smoke just poured out of it

Yep, that's what could be causing it. Try replacing the manifold or use jb weld on the leak

Could that also create a performance issue like a slight hesitation?

That ticking is definitely coming from that manifold. Try JB weld, if that doesn't work, replace it.

I'm not sure about hesitation, but your back pressure will lessen.

The manifold was still good no cracks and I put a new gasket still has ticking noise but it's much quieter and sounds like it's from the other side now so I'm going to do the same thing and hopefully it clears up after that! On a different subject my power steering unit to me sounds a bit noisy, it's always made the same noise and it's perfect on fluid and steers easily would it quiet it down if I replace it

Good to know! Too bad there isn't a way to silence it, but whatever. Haha

I have a 2005 GT and I'm having issues with 2nd gear. When I'm driving and go from 1st to 2nd it grinds the gear.. I have to baby it to get it to go into gear and its a 50/50 chance that it will. I don't have any problems with the other gears besides 2nd?? Any ideas on what it might be I need help
