Hey guys,

Before I go on, some of you may be wondering what the deal is with my bumper which I kind of messed up.

Well a few places that I have checked with are charging me from $700-$750...:( OUCH. So for now what I will do is screw it back up and leave the crack (its on the bottom grille of the bumper) until I find a J30 donor car with the same color (I hope I am lucky).

Either this week or next week, I am planning to detail my car inside and out (she will be a beauty). Then after that I am getting tints all around. I will ask you guys questions about detailing and tinting later on this week or maybe the next week.

Anyhow, on to my main question. Lately, whenever I drive my J30, it feels a little sluggish and it sure as hell doesnt feel the same anymore. Even my best friend drove it today and hes like, "Dude I dont know what the hell happened, but this doesnt feel the same as it used to."

Whenever I am on the highway or even on the road and I feel like I have to floor the car for whatever reasons/circumstances, it doesnt respond like it used to. It will be sluggish. Sometimes its frustrating.

I dont know what the problem could be. My car is 1993 has about 68,800 miles and I ALWAYS use Premium gas (it kills me with these gas prices).

I am thinking either of the two things. One is that my injectors may be dirty but with these many miles though?). If they are dirty, what is the best thing to use clean them?

The other thing I am thinking is that could be the throttle body? You guys think it might need some cleaning? If so, how do I do it? I used SEARCH and havent gotten much results.

Please help me out here. Thanks for all your help guys. Sorry for the long post. lol

Take care. Later...

A dirty TB wouldn't manifest itself as quickly.Injector issues show up as excessive vibrations, before they turn into performance issues.

My guess is one of these:-loose MAF connector-worn oxygen sensors (there is a self diagnostic procedure in the manual)-car is in failsafe mode for some reason, like it doesnt read read a key sonsor (like knock sensor), or is running too coold ( Tstat) or too hot (Tstat, radiator or other cooling issue).
