Default FIGURE THIS ONE OUT

Ok , here'* the scoop . i took out my maf screen , my car started running sluggish(from 4000-5000 rpm only) so i thought i would put it back in and everything would go back to normal. WRONG It'* still running the same , especially when the engine gets hot.
now, let me mind u i just installed new plugs(ngk irridium'*) new plug wires , new coils( accel'*) new o2 sensor( oem bosch) new oil change(mobile1 10w40), oil filter, pcv valve , fuel filter, air filter .i've been pumping premium fuel ever since i bought the car . the maf screen was not damaged.
any help would be appreciated.
thnx in advance.

ok , try this first, disconnect the bat. neg term. let the pcm power down, i would recommend like 30 mins if you can, it wont take that long to do it, but just in case of any other electronics on board that may reserve power. reconnect the bat. and start it. let it idle for 10 mins, then road test. this way the pcm will adjst itself to any new changes you have made. anytime you make a change, do this.
hope this helps you

Actually our Fuel Injectors are made by Bosch for GM BTW too. You'll find alot of the other components on our Bonnevilles are made by Bosch for GM too (IE: Relays, capacitors).

I would check for a loose or damaged Vacuumn hose that may have fallen off or got knocked off or even knicked when you were changing one of the above components.

I recommend just pulling the ecm fuse instead of disconnecting the battery

anyways, i'll let u know happens tommorrow and thnx for all ur help guys
