: If I had any hair, I'd be pulling it out now!

Hello all,
I own a 1989 Brougham 5.0L RWD. I love the car (when it runs right), but lately, it's been costing me a lot of money. My latest issue with the car is as follows; I think I may have a vaccuum leak. I recently had the cat. converter checked (thought it might be plugged), it's fine, I had a new muffler and tail pipe installed, a new heater core, spark plugs, wires, distributor cap, rotor, and coil installed. The car idles smoothly, when I take off, it seems fine until I step down on the gas pedal harder. The car starts jerking and feels like it's not getting gas.

Any and all help with this matter would be greatly appreciated.


Thanks

Check the Fuel Pressure, could be a bad fuel pump or bad filter?

Maybe the secondaries arent opening. Did it do this before the tune up?

Here is a vacuum diagram. I would check into the fuel issues, but you should also check the vacuum line for proper routing. I would replace them if that hasn't been done recently.

maybe check to ensure the wires are on in the right spots....I had that happen after a tune up in the fall...mechanic didn't feel it was right, and sure enough the apprentice had crossed a couple of sparkplug wires.

check the EGR? that could be doing it...or could be a problem with the carb (if this is carbed...dunno about 89) on mine I ended up needing a rebuilt carb to fix a problem like this due to the acellerator pump not working right
