Hey guys my 04 cobra runs and drives good until I do a few wot pulls. my transmission gets harder to put in any gear. If I park the car and come back to it, it gets better. It has 32k miles I’ve changed the trans fluid and I’ve added a MGW Short throw. What could be the concern?

I just finished rebuilding my 302 for my 1990 mustang 5.0. It is bored 0.30 over. I fired her up, bleed the cooling system & set the timing to 10 degrees. My concern is once the car warms up it doesn’t like to start. It has good fuel rail pressure, new injectors, pump, and fuel filter. I feel...

Hi there I have a 2012 Mustang 5.0 motor. I’m about to install the timing chains back on. Cylinder heads weren’t removed so the chains on the cams were left on. My issue is I did NOT follow the removal procedure. I believe I had just left the key way @ 12 oh clock and removed both chains in...

i installed a BBK off road Xpipe. I bought a set of eliminators but they aren’t long enough to reach the rear o2s on the Xpipe. Should I get o2 extenders? Does it make a difference if I use em or not?

hi there, I have a 2004 cobra with the following mods. Off road x pipe Catback exhaust Cold air intake. Once the vehicle is driven and warm it gives me a small idle surge. I’ve used carb cleaner sprayed the lines and gaskets to check for a vacuum leak but cannot find one. I installed a vacuum...

Hi there I have an exhaust leak from the Xpipe to catback. It’s a BBK off road x with Borla stingers and stock manifolds. Both piping is 2.5” shouldn’t one be bigger? Because it’s leaking right through

hi there I have a 04 cobra. Mods are intake, off road x and catback exhaust. The car is running a little rich, my front o2 are plugged in but my rears are not. Driver side I have my wideband hooked up and passenger side I have blocked it off. Maybe I have an exhaust leak? Causing it to go rich...

Replaced all my connecting rod bearings, Crankshaft Journals were in Okay shape so I decided to get brand new bearings from ford (oe spec/size).I made sure to use assembly lube on each part of the bearing/rod. As I followed the torque sequence: 177in ft lb, 28 ft lb, 105 degrees. I was able to...

I know your not supposed to run that size on that rim. But I googled and liked the look so I got two p255/35r18 Michelin pilots for my 18X8 classics. Will they fit on the rims?

i Just got ccw classics, 18x8.5 on the front and 18x11 on the rear. Has anyone ever ran p235 on the front? Was wondering if I should up it to a P265? Previous owner said the P235 worked really well on his cobra. I have toyo r888s for the rear, will I have to roll my fenders (P315). I have two...
