93 gs300 problem?

[juniorARISTO]

Ok will I have a 93 gs300 n/a has 194,000 miles on it. One day I was driving and it stated hesitating when gave it gas. So I drove home. I get in the car a cuple hrs latter I let it warm up and it drove fine. will as weeks went on it started to get bad my shifting on my car was hesitant(I really no nothing about how aut everything right check the fluid it was good. when i drove home it felt a little better on the shifting.

But when I parked the car came back out to turn it on it wouldent start. So I checked the codes it should the maf sensor. I got one from my friends car that was good put it on same thing...took a cuple of time to start it up it turned on gave it some gas black smoke came out from. black smoke came out from.

Will still did the samething(sounds like its missfiring). then the CEL came on again should same code(31 maf) so we checked the uhms on the sensor no good on the ground wire so I splice the to make new ground.(when bad sensor it well show below 5.00) will after all that still nothing does samething...so I going with that ecu is bad. What do you guys think?

if you can find which pin the maf is on the ecu, you can run a multimeter on that pin, then on the corresponding pin of the maf plug, put the multimeter on continuity and that will tell you if the wire has a break in it......does the car run fine if you just unplug the MAF??

you checked the spark plugs, you say it sounds like a misfire, maybe it is....

i have a uzz31 (1uz v8 model soarer) and i think the maf is fooked in that, every once in a while wen i start it, it will 'misfire' but if i unplug the maf, its fine.......then once its been running for 30secs or so, ill re-connect it and it will be fine! try that.....cud try a new ecu, but its not very likely for your ecu to just shit itself!! (although thats how electronics usually go)
