Hello
I have a 1987 mustang with a mass air conversion from Pro-flow (1992). The car runs not well at idle, its bump up and down +/- 100 rpm and smells like hell ...unburend feul. (If the engine is cold it runs perfect but after 5 min. it runs bad as discribed above)
The follow thinks i have did to get rid of the problem
- new IAC
- new TPS
- new O2 sensors
- new distributor cap and rotor
After this the computer gives no codes .....its passes the KOEO and KOER test!!!! But the car runs at idle still bad!!!
When i unplug the mass air it runs perfect. I know that when you unplug the mass air the car goes in "Limp" mode and shuts off several sensors.
My quenstion is ....... can it be that the the mass is broken. I have treid an other mass air sensor but is was not the same type. I read at this forum that the mass air must be calibrated at the size of the injectors (still stock). And the mass air sensors i have treid is of a cobra!!!!
The problem i have is that i live in Holland and over here nobody can calibrat the Mass air sensor.
Does somebody know were i can buy a new mass air sensor of the same type(Pro flow) without the tube where it's bolt on????
thx
