Something is definetly WAY OFF! Help me!!

Well i just get er back fromt he shop. Turns out it was the TPS Sensor. It was stuck at 5 volts. Replaced that and the Spark plugs, guy said there were like 3 different brands in there and they were black. So shes running again! 1st time ive driven it with the Cobra Intake! Seems like the horsepower is higher up in the RPM band, really holds the power longer, before it would just flatten out!! Oh, well again guys for all the help!
