BTW... being new to the forum..
The club found that Bosch plugs and wires do not last long and do not help our cars run good at all.
Don't know why...they just don't.
Recommened brands are:
NGK plugs
AC Delco Plugs
AC Delco Wires
Napa Belden Wires..
All good stuff.

UPDATE***
affter changeing the wires and plugs it is still doing it.
What else could it be?
Im thinking maybe O2 Sensor? or maybe some other ignition part?

So far I have done:
replaced Plugs, many differetn kinds
repalced wires, 2 different kinds
replaced maf
replaced tps
replaced coils even tho they were the same resistance before and after
cleaned throttle body
replaced o2 sensor
replace CAT with magnaflow
replaced all tires, balanced at multiple shops
after all that the car runs freakin perfect but the shudder still exists
what I am doing this weekend:
EGR valve and ICM
Does your problem go away when you press the gas and raise the RPM or put load on the trans?

It sounds like the same thing, when the tork converter is locked and put a little gas on it, it starts doing it and when i put more gas it gets worse, but as soon as the tork convert unlocks it stop. it does it the wors when the RPM is around 1,500-1,700 (locked)

Hey Bandit did you check your coils , if not check the resistance of each coil with a multi meter , tthe procedure is in techinfo.
Hans you should get yours scanned , sounds like your spending lots on good parts.

Lets get a few things right here...
On the 94-95 the TPS is looked at in a bit of a diffrent way as comapred to a 92-93... On these cars the Air flow meter is used a bit more... Almost no air flow is looked at as idle, so the engine idles, and it sees increased air flow as acceleration... They act diffrent... I seriously doubt a TPS issue here...
At this point I'm going to tell you to rplace the plugs and wires... These cars are notoious for killing off a set of wires, and if they are original they are dure for replacement...
These cars use a waste spark method where a spark is wasted, but for this to function properly the power had to get where it needs to go... The coil actually fires both plugs at the same time, but the cylinder on the exahust stroke requires less power to fire the plug so the rest of the power goes the the cylinder on the compression strok which requires more power to fire it...
Most around here seem to like the Napa Belden( spelling ) Wires... I like the Autolite Professional Series wires... Both are good quality... As well most use NGK TR55'* or AC Delco plugs... I have used Autolite in the past and thats a good plug as well...
Let us know how it all goes...
