believe this started happening after I install FMIC. When RPM's goes down to cero the car turns off, or goes back to 1,000 then down to cero,back to 1,cero, then stays normal.
Other problem is having is that it starts shaking. Thought it was the plug from the MAF sensor sense the clips is broken,but it was all the way in.
I believe the car is running TOO RICH cuz of the gas odors and sometimes does backfireing. Also, when u step off the gas pedal you hear some metal scrambling "like dropping to aluminum cans on the floor at the same time" kind of.
Driving back home from work noticed that if i go over 3,000rpm's car started shaking,and wen stepping on gas pedal it took long to go up on RPM's
I already check all the connection of the FMIC & everything is connected properly.Cleaned the cold air intake,lub it, cleaned throttle body and everything around it and still having these problems.
Was told that could be the TPS. Also that could be the BOV is taking all the air out of the system and supposely thats why the car struggles going back to 1,000rpm's even tho is not supposed to go down to cero. Was told that to fix the BOV problem I needed somehow like a vaccumm line or something to re-circulate air back to the system...
Any help you can provide will be really appreciate it. This is my daily car and I neede like asap.Thankz guys

Could be your MAFS. Try un plugging it and see how the engine idles. If it stays the same then its not your issue, if it gets better and stays solid rpm wise its your MAFS.
Also check your ecu, to see what codes if any its putting out.

ohh crap, so that might be another problem Jesus... I unplug it and RPMs stayed solid and a lil higher than when I had it on. When my car started shaking while it was on the side of the rode I unplugged the maf sensor and the car started acting normal,when I plug it back in again, rpm's started going up to 1,000, then down to cero etc etc till it got...and started shaking again lol.Morph wrote:Could be your MAFS.

ok ok... I found out what the problem was. It was the BOV. Its taking all the air out of the system, it stays open till it takes all the air out. So I need either a way to recirculate the air back, or an adjustable BOV. Any recomendations?
