When driving the engine/tranny kinda jerks and the service light comes on then it seems to go into a mode where gas peddle seems to deliver no fuel drives slow wile accelerating then smooths out round 40 miles per hour when shif into low gear it engages again and drives normally but won't in drive

The first thing I need to do is get it scanned for codes in the computer and let me know the exact code numbers not code descriptions?

The p0036 p0056 p0141 are all o2 sensor codes. Code p0102 is a mass air flow sensor code.P0451 is the evap pressure sensor code. The p2122 is accelerator pedal sensor 1 low voltage. So what do you mean the cats gone?As far as the codes go I would be looking at the code p2122 that put the vechile in reduced performance mode where the timing is retarded etc. Thats what happens when there is a fault in the throttle by wire system its a safety feature. Your going to need a scan tool that can read Live data and the throttle position sensor readings to diagnose the problem. The top fix for that code is the gas pedal assembly replacement but no guarantee that will fix that code.

With that mass air flow code the fuel tank pressure code and accelerator pedal position sensor code I think you have a problem with the 5 volt reference signal to them. Do you have a multi meter to do some testing?

No testing tools. Was told I should just get a new main computer found one for 100.00 and 200.00 to install. Do u think that may fix my problems. The garage I had it at for a work seem to think its a computer issue

I would check into the 5 volt reference signal that makes the most sense just throwing a computer at it would be a waste of money.
