Starting car in morning it starts rough the rpm fluctuating back and forth it does for about ten minutes. sometimes the car install i have to start 2 to 3 times. The car will warm up and it will shut off. I will start and off I will drive.The rpm will be okay running at 1500 and about 10 mintues after it will drop off to 1000 running good. If I start out early the car will shutt off or it will start to ****, hesitate and it will not pick up speed then I have to park on to side to warm up then proceed. After 15 mintues the car runs good and has pick up speed. I also notice that the trunk was very wet and the rear seat . I try to find out where but I couldn't. Front and the top was dry. Even the rear floor mat area was wet.

Re: 1992 mazda 323 car
Probably just needs a good tune up new plugs,leads,points the timing set clean oil fuel and air filters and the water leak is probably a perished rubber opening or glass seal or at worst rust holes under the window seals which allows water in but you cant really see where its coming from i hope this helps you even if a little thanks glenn........

Bleeding the fuel system is typically only needed on high pressure systems like GDI and Diesel vehicles, and only to get them to start if they run dry once.
If your engine keeps running but the idle speed moves up and down there are many things that can cause that. More information is always helpful. Does it always do it whenever the car is running? Or does it only do it conditionally (IE Only when 1st started in the morning, only after warmed up or getting off the dreeway, only with AC on or at night...describe as much as you can.)
Most newer cars have computer controlled idle strategy that wants to idle the car cold around 1000-1500 rpm (After an initial higher rev called a FLARE) and then bring it down in 3 or 4 minutes to 700ish rpm. If it CANNOT bring it down by normal means, then many resort to something called FUEL CUT IDLE where it actually turns off the fuel momentarily and the RPM will drop because the car is stalling and running out of gas...then back on and it starts to rev back up and when it gets too hiugh it turns back off. Cars that do this can have annoying surges from 500-2000 back and forth at idle forever.
a vacuum leak or MAF meter problem can cause rough idle. ALmost any engine code that turns on CHECK ENGINE lamp may be suspect, does it have any current fault codes?
As well, consider Sticking manifold runners, EGR systems, and temperature sensors all can cause surging, so can a defective Oxygen sensor, slightly jumped timing, and dirty throttle plates the ECM wants to close more but they wont due to dirt. If its not something fairly obvious, it may require deeper checking.
These vehicles have a built in antitheft system. When switching the ignition you interrupt this system.
You will need to do a system relearn after the new ignition is installed. It will not start until the new ignition is installed and relearned.
Step one. Put key in ignition, turn forward 2 clicks until right before it should start. Keep like that for ten minutes, NO LESS.
Step two. After the ten minutes, turn key back to off position for 5 seconds.
You need to do steps 1 & 2 a total of three times in a row without trying to start the car in between. The whole process should take roughly 30 minutes. After the last time waiting 5 seconds in off position, turn key forward and attempt to start the vehicle. Remember no less than ten minutes when forward, maybe do ten minutes and 15 seconds to be sure, some people even do 11 minutes.
Some times this problem comes from lack of coolant wather. or a watherpump faliur.
check pump drive belt. refil coolant, remember to refil radiator too. check under car when running for leek, dripping. check oil cap inside after running, if inside of cab is foam like, it is possible a burnt topgasket. if none of the above, replace temp censor and thermostat.
Could be many things Mass Airflow Sensor, coil pack, O2 sensor , plugs ,wires right down to fuel filter. . It all depends on how well the car has been maintained . If you know the maintenance history of the car then you can start crossing things off one at a time till you come across something that hasn't been changed in a while like plugs for example .
