MAF or TPS problem

Bibo · Post by **Bibo** » October 31st, 2005, 2:43 pm

hi...i've been watching this forum for a while now and so far it has gotten me and my 94 mx3 out of all the jams but i'm affraid this time im stuck. here is the deal. last week my car started acting up. whenever i accelerate fast it's "choking" as if its not burning all the gas. in order to get it to move i have to take my time ...revi it SLOWLY to 2500 to 3000 rpms and then slowly release the clutch. then i have no problems. the idle works great. i tried exchanging the fuel filter the cap and rotor air filter and some other small things befor i realised it might be the TPS. i exchanged that one too from the scrap bt still the same. i even mesured it with the multimeter and it reads within the normal parameters. the engine check did not give me any codes. so now im wondering if it can be the MAF but before i go ahead and exchange that one too i wanna make sure that is the problem cuz its friggin expensive (1400 CAD at the dealer and 125 at the scrap).so there u go this is my case. anyone have anyy suugestions?

thanks

maybe you could check the plugs, plug wires and timing etc before that....

If it has more than 60000 miles, then maybe its time to replace the O2 sensor....

I am having this same problem. I am going to check the O2 sensor and I just replaced my MAF, maybe I need to re-coonect it or something Ima check it all out in the morning.

I'm having the same problem, did anyone find out what it is? I recently replaced my spark plugs and timing belt(retimed the engine too obviously) Also, it doesn't happen when the car is cold, does this make any difference?

sounds like a bad TPS adjustment, mines doing the same thing cuz i messed with the TPS just to see what it would do and im having the same problems u guys are....do the guide and readjust it and that should fix it if not probably a sensor.
