Need some expert advice here guys...
Been having some bad problems lately. Distrubutor went out. So I decided to replace all parts, plugs, wires, cap/rotor, ignition control module (TFI module), coil. So basically all electrical parts are brand new excluding the MAF and o2 sensors (o2's are like 5,000 miles old).
It has a noticable miss down low (stumble maybe) and it's definity down on power. I ran a cylinder balance test and it said that #7 injector was weak. Two weeks ago I ran a comp test and got perfect numbers across the board, so that's out of the question.
So, today I swapped the #7 injector with the #1 injector and the problem mysteriously went away. But it still drove like crap.
After about an hour of speculating with my buddy, we looked into my MAF, which is a 75mm Pro-M Bullet cal'd for my 24lb injectors. So, I took the sensor out and cleaned it (noticably dirty), put it back in and it still drove like crap. So we thought to unplug it and see if it died. Suprisingly, it ran the EXACT same way. No notcable chance in RPM and it obviously didn't die on us. Drove it around and no different than how it drove then when it was plugged in.
So, my question is, if the MAF (and everything else along with it) was good, when I unplugged the sensor, shouldn't it have died or struggled to idle until the computer adjusted it?
If it should have died or stuggled to idle, is my MAF screwed up?
What else should I try guys? I've got no codes; all the electrical parts are brand new. Do o2's usually go bad w/out throwing a CEL?
Thanks guys!
