SOURCE: When I try to accelerate my car has no power!

There could be a couple of reasons. Yes a tune up would be nice. But my not fix the problem. If you are not losing acceleration on straight away but on hill, then it could be the torqe converter. Also have your MASS airflow sensor checked and air filter.

Also check your fuel pressure at the fuel rail. Get a fuel gauge and look for a port on the fuel rail for a port that looks like the valve on the tire. Screw it in and crank the car. You will have to call the part store to find out what pressure it is supposed to be. If there is low or eratic pressure the its the filter or pump

SOURCE: engine speed will not rev over 4000rpm

Sounds like a fuel filter issue. If the filter is clogged or is getting to the point where it's going to be clogged badly the amount of fuel going to the engine will be restricted. This would cause your stated problem. Theoretically there isn't much of a need to go over 4000 rpm unless you are racing with the car but I think most bimmer owners can understand where you are coming from:) As far as the 1993, I'd check all your intake piping and vacuum lines and make sure there are no leaks whatsoever. An easy way to check is to have the car running and spray carb cleaner on the intake piping and such and see if your revs increase, if they do you've got a leak. Hope this helps! I'd be glad to help with any other questions you might have a please don't forget to rate me.

SOURCE: 2000 corolla sluggish when accelerating, fine at higher RPMs

Try changing out your distributer cap and rotor button. Let me know if that solves your problem.


Thx

I'll keep this very short. Replace your Mass Air Flow sensor(MAF). You can get a used one usually and be just fine. Check out silverstar auto recycling in Fresno, CA.. Great service. I've done a lot of business with them.

Disconnect the battery completely, try turning the key with the battery disconnected. Put the battery back together. The check engine light should be off now..

I have a ls400 1993.My car starts fine. But when I accelerate it moves very slow them picks up speed after a few minutes. repeats at every stop... Please help.


Throttle position sensor may be faulty. They do not always show fault codes.

There is a vehicle speed sensor too that may also be at fault. but the TPS is easier to get at initially.

We have a 1993 Mercedes 400 SEL. The climate control unit has a problem where it will keep turning on and killing the battery.We have been disconnecting the battery cables every time we shut down for more...


The ASR and ABS are voltage sensitive, so each time you disconnect them from power, they will reset. To cancel the ASR light, start engine then turn steering wheel full lock to right, then lock to left...ASR should extinguish. ABS light should then go out once you drive above 8 mph for 100yards or so. Until you can have the climate control looked at by a professional, I would locate and remove the fuse for it when you park up. Much better than disconnecting battery.

I gave a jump to my 1993 400 sel now the abs and asr dash lights will not go out and the speed ometer does not work


Check fuses, you are not supposed to "jump" MB thats why they have forever roadside assistance. You charge battery while disconnected and reconnect to start.

1992 Mercedes 500 sel trany sliping


Probably a modulator, however check that the "bowden" cable is properly adjusted (this is the cable that does the "kickdown" and also goes to a vacum /valve.It is simple to adjust, basically with the engine turned OFF, check that the 2 pointers (like arrows) align, (one is on the cable). Being a merc it pays to have the tranny properly serviced, and its filter changed at least every 2 years though merc says 60,000k's. And the one thing that will kill a merc transmission is the WRONG oil, it has to be according to the spec sheet which is in your user manual.(lots of tranny shops use anything!)
Also check the dipstick for discolouration/and or burnt smell.
