Engine keeps stalling?

I check codes when you turn you key on and off a few times. The light blink 12 then 55, does any one knows what it means?

12 is battery or computer recently disconnected. And 55 is end of codes.

Do you know how to fix it?

All that means is, you you either disconnected your battery within the last 24 hours. And / or when u start it, turn it off, ext it resets the computer. Then of course 55 says it's the end of all codes.

Have a 3.O caravan. Car died while back so I emptied the cat conv. That then gave me a code for 02 sensor. I replaced that and still she starts but after a few miles of driving the gas pedal looses pressure and the only way to get it to go any further you gotta tap very fast on pedal but after a min she putters and dies and will fire back up only to have poor idle and when you hit gas it goes to die again. Did cap and rotor and fuel pump does make sounds when key turned on. Please any info would be great

Engine stalls after fast acceleration

Hi
The check engine light has not come on, fuel pump presure is good I think I found prolem verify for me if
you think the same.
I started a proccess of elimination by disconnecting all
vacum hoses and inspecting for leaks did not find any
but when I disconnected the vacum hose from EGR valve to selenoid the engine ran smoother and took car for test, it did not shut off at all but notice at idle
car smoked when connected hose smoke went away
now my next test is to remove EGR and clean it. If it does not work them it may be selenoid,
Question how can I test selenoid for damage?

My 1995 Grand Caravan starts fine (from cold) and runs fine for around 15 minutes. After that warmup period it starts sputtering as if it's starving for fuel and eventually dies. Once it cools back down, it'll run fine again (but for only another 15 minutes).

This is very consistent.

This problem began after having a new (and cheap) transmission put in. I've had both the transmission mechanic and a 2nd independent mechanic look at it without luck. The 2nd guy is guessing that the transmission guy cracked the fly wheel when dropping-in the transmission. The transmission guy said this isn't possible because it wouldn't run fine at all then. Having that checked will cost too much in labor so I'm kind of stuck.

The transmission guy thinks it's a bad computer (engine computer near the battery) and unrelated to the new transmission. He said a replacement would solve the problem.

The independent guy checked the fuel pressure and changed the fuel filter just in case but that didn't help. He's not so sure about the computer theory.

What could be causing this problem that relates to the engine being warm?

As I drive my vehicle, 5-10 minutes later, all the lights go dead and the vehicle spits and sputs and dies. Then it wont turn back on for another couple hours, just for a short time. Battery is brand new, just replaced it in thoughts that was the problem. Then I tested the alternator, but it was taken off at the time, since I cannot really drive it anywhere to get it tested on the vehicle. Any ideas on what it could be, if the alternator is bad? Also, all connections were checked.

Yes, lights go dead, CD player goes dead, heat stops working, and so on.

Like many others while driving it simply cuts off, when in reverse its the same, when turning a corner or slowing down, I use gas cleaner, oil cleaner, change fuel filther, check for vacum leak, loose wiring, maybe need to change spark plugs and wire. I change oil, put in oil pressur switch. Run fine then start the same thing, cuts off

my caravan stalls whenever I slow down. When I am on the freeway, it does not stall until I slow down to about 10 miles per hour. The check engine light is also on. The van always starts right back up after stalling. This has been going on for about two days now. I also smell gas when I do start it up.
