From a dead stop when I get on the accelerator the car really bogs badly and I am not sure why.

NO CODES!

I have new:
plugs
plug wires
fuel filter
newer cap and rotor (no carbon buildup)
TPS sensor

Does anyone know what may be causing this?

Did you reset the timing at the dizzy after your tune-up? That would probably be the biggest problem right there. Could also be that your TPS isn't zero'd too. I would start with those things.

Shiz, you could be right about the Dizzy being off... I moved it a little before I took it in to the shop...hopefully after I move it back it will resolve the problem.

Do you think it may be running too rich or lean with the problems I am having?
or is that not the case at all?

delScho

I doubt it. Sounds like it's all timing to me. Put a light on it and set it dead nuts. Make sure it feels right before advancing any farther.

EDIT: Make sure to reset the ecu after you reset the timing. Might not make a world of difference, but it could help a little.

your problem is highlighted did you set your TPS after you installed it?

Actually I did not set the TPS - I figured that the shop would do that when they installed it yesterday.

How to I check it to be sure that it is set correctly?

using a voltmeter. You tap the middle wire going to the sensor with a safety pin or needle; this serves as an extension. Then you ground the black wire on your voltmeter to something on your engine ( i use the battery ground), and you read off of the pin using the red wire. At idle, (no throttle) it should read ~ .45 , at WOT (wide open throttle) it should read ~ 4.5. Hope this helps, i'm having the same problem with the bogging on acceleration, only i can't get my TPS to 4.5 at WOT. I think i just have a bad TPS sensor.

cool - thanks for the info!
unfortunately I dont have a voltage meter to check the TPS sensor, I should call the shop to see if they tested it after installing it.

you can pick up a voltmeter or multimeter pretty cheap at radio shack, lowes, home depot, etc...

How do you do this? My dist is replaced, I didnt know I needed to set the timing again, never did that before.....
