My first post! yay! anyway...I have a 94 ATX that is just about to turn 100k. The 60k was done on time 3 years ago, but my 3.2 just seems like it doesnt want to perform like I'm used to. It just seems kinda laggy. What can I do to get the pep back in my SHO short of doing the 120k service early? or should I hit up the 120k service now? Thanks SHOers, I know you guys are smart.

Welcome to the forum, we arent smart, but we aint dumb neither.

You first need to see if there is anything recorded in the memory via a CE light that may have come on. Do this by checking your codes (see www.shotimes.com) for a detailed how to.

outside of that, without any symtoms or other details, your problem could be any number of 100 things from sticky rear brake, to a clogged cat. I would not just crack into a 60k with the hopes of "it may help performance". We would need more of a discription outside of "iIt just doesnt seem to feel the same".

Find out the symptoms....check a few previous posts, and get back to us.

again, welcome.

try just a basic tune up , like new plugs and wires and stuff like that, and ! just my opinion ,but i always up until about 6 months ago used strictly motorcraft plugs and wires and this last time ,i tried autolite plugs and taylor wires and i swear my car is driving better than it has with all the other maintenance things i did combined.......however i would really need to drive it a bit to be able to really help you !! ...good luck !!!!!!!!!!!

First thing to do is not spend money unnecessarily.

One of the most common problems is a dirty MAF sensor. Try cleaning it with some electrical contact cleaner.

Also, when was the air filter last replaced? TPS sensor? Any codes stored in the computer?

like a air filter or tps is not wasting money ? and a dirty maf, lol .....i say it is less of a chance of sagging performance than bad old plugs and a new set of wires ! like i said without actually driving it , i , like you ! can't possibly know whats wrong !.....but i say new plugs and wires a fuel filter an air filter and a tank of good gas works pretty well on everything to start , if it rides lousy after that , then he will have to keep digging ...and wasting money !!..but i wish him the best anyways !!

Did I say to replace all those things? NO. There's a big difference between throwing money at a problem, and actually diagnosing it. There is no reason to replace plugs and wires that are only 46k miles old.

A bad plug or wire will cause a misfire. A dirty MAF will cause a car to run lean, and as a result it will feel slow or doggy, and lack overall power.
