Question about 1994 BMW 3 Series

1 Answer

Caddiladic Converter Hi, recently having problems in my 94 320i where it jolts and the revs go up and down. Have taken battery out and put it back in and it worked fine. Happens every now and then. My mechanic advised it may be this Caddildic Converter, blocked and causing it to lose power. Can you advise if this can be done at home with welding gear etc

The reason the car jolts is because off the revs going up and down,but this not the problem,my main suspect in this case would be dirty or blocked injectors.The first thing buy a can of fuel cleaner and run it through your system you will be surprised,The other simple item that will cause this is an clogged air filter.adrian

2006 Pt Crusier P068a code is all im getting with key dance.. dont know what that means but my battery light is on and car boggs down when i give it gas. thinking catyalic converter?? any help please


Hi,maybe the best place to start is the alternater,if the red light is on and when you try to rev up the engine it gos to die,one other check is to put a multymetre on the battery it should be around 12v but when you rev up the engine it should go to about 14v,so try reving if it stays the same or gose lower the could be alternater.
all the best

Reving problems


The high rev sounds like a vaccumm problem. What year is the vehicle? If its
newer than 1995 it more than likely has a lot of vaccumm operated parts. I would check for leaks and get that out of the way.

H2 transmission problem


Hi
The screen will have nothing to do with it. I would however take the car back to the person that fixed it as this is most likely a fault they have made. things you can check yourself.

1 check the gearbox fluid is to the correct level
2 check the slave cylinder to see if there are any signs of damp around it

ask the place where you got it repaired to check the crank sensor,the slave cylinder, and the torque converter.

The toque converter may have been damaged when they fitted the new transmission, although these are funny parts and can just break down by them selves.
the torque converter is what turns the rev's in the power basically in converters the power to drive.

Hope this helps.

Regards
Dan

My car has no power and i recently had the catylic converter taken off. does this make the car somewhat **** when pressing the gas or what else could it be. my montecarlo has 105k miles


You must put the catalytic converter back on your car because you now don't have any compression and that is why you have no power. Also it is federally mandated that your car have a catalytic converter. Your Chevrolet dealer may have to put one on for free because of the dealer being required to replace certain emissions-related components depending upon your state.

Idle up and down to 1500 rpm at first start when cold


Have you by any chance taken a multimeter & tested your TP (throttle position) sensor ? If you think you might know how, let me know & we'll guide you through it. If not, at least take wiring plug off & clean both plug & TP sensor contacts with contact cleaner, and inspect for any corrosion while doing it. When putting plug back on, use a little di-electric grease in the connection. Have you sprayed your throttle body & throttle plate good with throttle body cleaner recently?
