I often see the fixie community roasting people with no foot retention, so I’m wondering if single speed riders have a similar pet peeve about missing a rear brake. Is front brake only considered unsafe or something else here?
Hey everyone, I am completely exhausted with this car and desperately need some fresh eyes on this problem.
It is a 2006 Ford Mustang 4.0L V6 Automatic 120,000 miles
The car has Severe rough idle with a nocassional "thump-thump-thump" shaking
Also terrible acceleration and major lack of power.
The gas pedal has a weird "dead spot." There is a tiny sweet spot where it accelerates normally, but if you press it too little or too much, the engine completely bogs down and doesn't respond as it should.
Occasional backfiring/popping farts from the exhaust
I bought the car running poorly, was told it just needed a tune up. Replaced spark plugs, plug wires, and fuel filter for motorcraft new ones Shaking remained.
Needed and did the timing chains, but a tensioner broke. Fixed that, but the engine developed a massive, loud metallic/plastic ticking. Found low compression, resurfaced the heads, but ultimately decided to swap the motor.
Put a known good, used 4.0L engine in. Sympthoms remained
Recently we noticed a glowing red thing from the engine bay. The catalytic converters were heavily clogged with carbon and smelled like rotten eggs. We cut the cats out, cleared the blockage, and welded a pipe in. The problem still exists
On the previous engine we tried a cigarette smoke test for vaccumm lines, but didn't find anything obvious.
Oh and a few days ago we replaced the ignition coil
On the old engine, it threw a p0171. The new engine is currently throwing the exact same code
I've been reading up on intake manifold gasket leaks on these 4.0s and plan to check that next.
Does anyone have any ideas? I will answer any questions or provide any info you need. Thank you
