Well when i get on it about 3/4 the way or all the way it seems like it's missing or like the feeling my tires are slipping in a way. it's felt like this before and then at it's worst point it wouldn't idle right and didn't drive right and all it was were plugs and wires. so what else could be causing this. i sort of have a feeling it's the plugs or wires again but what would be making them go bad so fast?

I dunno but i'm having the same problem--do a boost leak test first, then check the plug wires for water damage---there's a great post on there somewhere about thsi...unfotunately i just got off work and am exhausted, but do a search on this particular forum--if no dice i'll look tomorrow
The post is an FAQ from MSD--just checked the website though, couldn't find it

The hesitiation could be a bad TPS sensor that is making the car hit fuel cut in partial throttle pulls. How old is the car and have any of the sensors around the throttle body been replaced?
I had a similar issue, although I'm not sute the same one due to your differeing description, and it was a bad TPS sensor, and then my ISC motor died too. Time kills electronics.

#1...whats an ISC motor?
#2...I really wanna find that link---if your first plugs/wires went out b/c of water in the spark plug wells it is -POSSIBLE- that the water got right back in there and killed the second set---since they're new you may be able to bitch and return them, depending.
just something to keep in mind---
if it is the TPS that's easy to check too (and free)

An ISC is an Idle Speed Control sensor, as for what is does exactly i forget? but anyway the car is a 97 with 57k miles. I'll take it to a mechanic to see about the water in the plugs and if that's not it i'll try the test on on the TPS.

a mechanic prob won't be able to see it any better than you on the wires, damn I really wish I could find this link about how to tell---basically it looks like a small white pinhole in the plug wire boot--the part that attaches to the plug...this is an indication of moisture (often not visible to the human eye) that is causing arc-ing

my car is doing this. at full throttle around 4500rpms the car sounds like its missing and back fires and looses alot of power. it started doing this 2 days ago. im thinking maybe it was a bad tank of gas? what are symptoms of the knock sensor retarding the timing?
im going to change the plugs. the wires i got are bwd automotive 7mm wire, and i hadnt been having problems with them before.
