I'm not sure whats going on, but my stang is acting weird. I recently had stage 3 cams installed, along with all the other bolt ons and full exhaust with a 3000 stall torque converter. The car ran like a beast for a month, but now it seems to be slow all of a sudden, like I'm haulin a mack truck hooked to my rear bumper. No check engine light. I'm wondering if a cylinder is not firing or something, cuz the shop who did the cams forgot to plug in the coil on the 1rst cylinder drivers side. I drove around for a week on 7 cylinders before I figured it out and plugged the coil back in. Car ran great afterward but as i said, has run with less power since yesterdaySo has dumping fuel into a nonfunctioning cylinder for 500 milesfouled a plug or sumthing? My tune shop said that should not cause problems unless I have driven a few thousand miles with a non-functioning cylinder. Any thoughts on what I should do? If that shop effed up my car by forgeting to plug that coil in I'm gonna be pissed.

 

I would take it back to the shop. Didn't you get some type of warranty?

 

Going to agree if nothing else just tell them how it's running and ask them to take a look if something is wrong you don't want to drive with it longer and make it worse.

 

Well, strange but I took the car out todayto see if this was some kind of anomaly, and the car is running like a beast again. Tool a stopwatch with me and I got a 0-40 mph of 2.3 seconds and a 0-60 of 4.4. I can't explain this.

 

Now when you had the cams done you had them put in new spriings as well.. correct..??

 

Yes I had the springs changed as well. Like I said, the car is back to its beastly form today. I have no idea what yesterday's sluggishness was all about
