I was excited to pick up my car today and my excitement turned to frustration as my car runs like crap now.

I have a 90 lx automatic 5.0 The car ran fairly strong I felt for a complete stock. Today I took it in to the exhaust shop and had this installed.

No my car has not torque at all I it is 99 degrees out and it will not even spin a tire in drive. In addition to this I took it out on the highway and it took forever just to get up to 80 mph it is running slower than my 99 grand am. The tach is bouncing all the time especially at idle. Does anyone have any idea what the heck this could be? Any help is appreciated.

Good news is it sounds good.

Nevermind I went out to check things out and noticed hey I only had 5 spark plugs hooked up. So I drove it for about 15 miles on 5 plugs hooked the other three up and wow now we are talking.

haha... good

i was wondering if they fried your o2 sensors or cut the wires and it was pig rich.

nitrous-bob that is exactly what I though at first but he said he hooked them up and there were no problems then I got to thinking that it was running like it was not on all cylinders and sure enough it wasn't

CHECK MATE
