I need your wisdom.i have a bmw e36 325i 1992.When I'm going to start at a traffic light or anywhere I try to start the normal car. It does not start well, it is as if it were drowning and catching on again. as if I gave him a micro heart attack. When I walk at low rpm the car starts to pull, and if I add the clutch, the car's rpm goes up and down as if it were turned on and off. I need help pleasethe damage is not constant sometimes.
Welcome to the Forum!
If the idle is going up and down, there's a good chance you have a common vacuum leak. The easiest way that you can do is to look at the big rubber black hose between the air filter/ MAF and the throttle body. Squeeze it to see if you can find any cracks, splits, ect. as they like to hide in the ribs of the hose.

When you accelerate from stationary the engine does not accelerate well? When you are coasting at rpm it bogs down and when you engage the clutch idle goes up and down?
At a guess
1, Idle Control Valve needs cleaning also called ICV
2, Vacuum leaks
3, MAF is bad (Mass Air Flow sensor) you can temporarily test this by disconnecting the MAF then driving the vehicle
be careful interpreting a change in behavior from disconnecting the MAF as meaning the MAF is bad. this is not completely true.
disconnecting the maf puts the car in default fueling strategy and sets a code....
determining if a MAF is bad would require reading live data.....
'95 325iS - auto to manual swap done!
+1
For it would take the MAF out but also show a greater chance of vacuum leaks more than a bad MAF.

Well I already told you that the car will connect to the checkup computer. now it showed three failures
the temperature sensor was at 150 c. the ac had problems, and the tps failed, the codes were erased and now we try to read the car again and problems, it connects, the process begins and it disconnects, I think my car has its own life hahahahaha
well we return to the problem. after checking my computer, we found these codes. shows that the tps is in trouble, but I put it back, here I leave you I hope your comments greetings

The first code will be the TPS, that can be tested to ensure it is in good working order.
The second code, I would say if for the DME, or engine computer. Check the fuses and control relays for good connection, and that they too are in good working order.

tks bro
well I found the fault. It turns out that the motor oil came out and I filled two spark plugs and put them in short so I just cleaned and thanks to all
That would cause miss-fire codes too, so it's a bit odd that you didn't see any. Yes it will cause the car to stumble, and miss. I hope you replaced the valve cover gasket and the profile gasket as well, otherwise the oil will leak back in and you will be back at square 1 again.
