Car vibrates in 1st gear when accelerating too quickly. Check engine light on. Dealer says catalytic converter needs replacing $1800 (incl labor). Do I have two problems or one? Failed emissions test.

it just doesn't work anymore.

Details first problem. Car would not start after starting well for numerous times, replaced main relay, starts fine.
also car stalls as I drive down the road will not start for several minutes, Getting worse and more frequent. Someone suggested ignition switch.
Gear selector will lock in park I have to use the key to move it out, so I park and start in neutral.
After a recent trip I noticed the temp and gas gages dropped to the bottom and no longer work.
Any Ideas???????
P.S. I dont know what type of engine this is.

it's a 1500 5.7l

pull fuse and it stops running

please give me alittle more insight on this problem.can it be something simple.

Will the bolt sheer or the assembly strip out if the tool keeps tightening the bolt?

i remember that it came on a couple of months ago for awhile and i remember filling up one day with regular gas and it went off, but now its back on. i had a cat put on a few years ago. i hope thats not the problem.could it be the rear 02 sensor.

Iam getting spark and no codes i changed the cam sensor and crank that did not help and i put ether into the air in-take still will not start

According to the dealership the front brake pads are completely worn. They want to replace the rotors at the same time. This seems excessive, particularly given the low mileage.

please help me

the sport trac just started a large amount smoke from tail pipe and has lost power while driving. it smells like the gas is going through the pipe. as soon as i slowed the engine would cut off. it restarted but i had to keep gas pedle to floor, most i could get for speed was 30 miles hr.
i traveled 10 miles and used ablout 20L of gas. it seems like the gas is just going out the tail pipe.
what would cause this?


Tried replacing steering pump and wheel bearings. still the same. it takes about 20-30 minutes on the road to warm up and start doing it. Any ideas?

trans slips in low gears, error code says a soleniod is stuck open but the shop thinks due to this code and gear slippage it should be rebuilt
