Hey guys. I got a problem and dont know whats going on. My ECU said i needed a new maf sensor (mass air flow sensor) and once i installed it, the ECU said i needed one still, and the problem of my car did not fix.. The problem is

Sometimes, when i start up the car, it wont start at all, and when i do start it, the rpms are around 1000 to heat up. Once i shift gears, my car sometimes stays on, or just dies. It is on for a second, and then dead. Also, when i rev up the car, it wont pass 3000 rpms, it only comes near it.. It also jumps from 2000 rpms to almost 3000. Once it does that, my car starts struggling and shake. My mechanic doesnt know whats wrong and is going to talk to his mechanic friends. I hope its not anything with the transmission.... or else its to the stealerships.............i mean good ol' dealershipp.. :\

 

That sounds like a typical maf sensor failure. But if u installed a new one it should have begun to run normal. Did u try reseting the ECU??

 

+1... you need to reset the ecu after replacing a maf that threw a code.

 

Did you check anything first, or just replace the MAF assuming that was the problem?

Assuming you cleared the codes and the MAF code came back, then it's likely a harness issue. Some have fixed issues like that by grounding the MAF, or it could be some corrosion within the connector, a damaged wire, etc.

 

Il try resetting it, but how would that help? Yes my check engine light came. It gave me the code for a maf sensor.

 

No, did you reset the codes after you replaced the MAF?

 

No i did not reset it after installing my maf sensor... I bought the mass air flow from a junkyard, guaranteed to work.

 

Then do so, see if the symptoms are still there, and if the code comes back.

Instructions are in the stickies.

 

My car had similar problems when I installed the TPS on backwards...

 

can you help me define what a tps is?

 

and il try that, thanks pmohr. il let you know how it goes

 

TPS= trottle position sensor

It's attached to the trottle body, near the maf sensor. I doubt that is the problem though if you never touched it.

 

check the maf plugs that should do it

 

well my personal mechanic came, he said he put my old MAF on his neighbors 95 gle maxima and it brought up the same problem. My current MAF i just bought from the junkyard did the same as my old. He picked up the junkyard one and its getting another one.. i hope this fixes the problem :\ :\ :\ :\

 

So you have or have not followed my suggestions above?
