Problem idling when sitting still with engine light coming on while sitting. Idles rough What is a code 21 on the engine diagnostics check, ambient or O2 sensor?

I recently got a 93 caravan. It already had a miss so i did a acomplete tune up, plugs,wires,cap,button,air filter,fuel filter. It helped the miss but not entirely,some of the plugs 2 of them looked as if they were bad,not flooded withe gas just not firing looking. I did the code thing and it read a 12 and a 37,the 37 is a ptu solenoid which handles the tranny junk so i either read it wrong or something. it seems like thats not it although i havent changed nothing. i dont think this would make it miss at idle or all the time am i wrong.this thing has been a pain. the wife has got the monetro and i got this since it runs like crap and its myy fault. but i dont wont her to egt stranded but if i can get it goin good then im back in the saddle of the 4wd til then i need help. it hasnt died yet but runs like crap i used to like cars til my last 2 the camry hasnt moved in 2 mnths. I told you so she says....get me outta this mess, should i drive it to the scrap yard and give it up 4 a lost cause or set it on fire and roll it down the mountain.if i can get it run its by bye birdie but til then chugachugachuga off to work i go,did i mention the heater works great and it has built in car seats for the kids honey.

how can you check and see if the fuel pump is going bad or if it is pushing to much fuel?

car will stall when raing or in a drive through car wash, may not start when raining, or driving through puddles

emission wont pass what can i do.

How can I identify where water that shows up under the driver's feet is coming from. It's not from the taillight, the back floor and spare wheel well stays dry. It's not from the A/C, it no longer hold freon and hasn't for years. And it doesn't matter whether it rains or not. I also can't find any assembly drawings that could help.

after it starts it kills,hard to start.kills when driving,i have replaced dist.dist.cap&rotor,plugs&wires,coil pack,o2 censor,thermostat,coolant temp sensor and crank pos. sensor. fuel pump has 40lbs+ pressure. fuel loads up.strong gas smell.could it be the injectors?fuel pump getting week after a few minutes making it not start?it ran good for 2 days then the problem started all over again

Tranny fluid is spraying out. Bad seals.

got to replace fuel filter and pump in the tank how do I know what size tank is?

THE DODGE NEON, DODGE STRATUS AND DODGE CARAVAN 2.4 HAVE THE SAME ENGINE i had to change my engine i caled l chrysler they told me to take it to a dealer i called the dealer they told me "this will be a very expensive job" chrysler refuse to tell me how much of the bill they will foot so i took my chances and put a use engine from a dodge stratus that was the end of my problem chrysler was saying maybe the mechanic damage my car the first time i had it fixed so i could not trust them now is the mechanic why i am having end play problems. duh

My dodge headlights keep going on and off. I removed the switch to check it and realized the headlights stay on when the car is on. I assume the headlights work digitally is that like the fly by wire design? how do i fix it?

Steering Wheel Shakes or Vibrates Erratically When In Park & In Idle. (Like At A Red Light) It's Fine At Normal & High Speeds. (Come to find out it's normal for a 2.4 4 cylinder Dodge Stratus to do this).

Is it critical to change the timing belt when changing the water pump. This vehicle is a beater and dosn't travel far from home. I would just like to get maybe another year out of it.

I have had to replace the engine in my 2006 freightliner sprinter 3 times, because the turbo sucks alot of dust! I clean the filter once a week, and buy a new filter every 2 weeks! Is there any other solution, and have they redesigned the air intakes for the new sprinters?


What is the anticipated average annual maintenance costs?

Started a day ago my break light came on. I bought break fluid and five minutes later my light came on. This morning I checked it and it was empty

my passenger front side tire does not respond to my steering the driver side tire does

This just started last night, truck started very weak and died as soon as I let off gas pedal truck dies. I did this over and over, finally said screw it, put it in gear and drove it back home (not letting off gas pedal, I only lived two blocks away). Pulled in driveway and it died when I let off gas. Sitting there wondering what the problem was and I heard and felt 3 pops while sitting in driver seat, started truck just fine and ran fine. Started and drove fine to work this morning...but when I went to leave work it did same thing again. I have no clue where to even start...
