2001 Chevy Malibu uncontrolled acceleration

47,000 miles on this 2001 Malibu LS, had trouble stopping, felt like I had the gas pedal & brake on. After managing to stop, let off brake & it accelerated by itself gradually to 55 & I had to hit brake to slow down. I put it in neutral & revved the engine thinking maybe something was stuck. No help. Turned on & off the cruise, again no impact. I floored it going uphill & it finally stopped accelerating. The RPM's seemed to be jumping by itself up to 2,000, stuck mostly at 1,500.

Put on analyzer & the only code it came up with was V1040, Loss of EBCM/EBTCM . Electronic brake control module. I was told that may not be the real problem, but just because I had the braking issue while the car was accelerating.

Any ideas?

Throttle position sensor faulty. MAF sensor? Did the dealer read the code? See if there are any Tech Service Bullitans on this. Under warranty?

I haven't checked service bulletins, & it is not under warranty. Thanks for the suggestions!

I just wanted to post that it turned out to be the cable to the accelerator needed lubrication. I replaced several sensors & it still did it. Then found that the cable was sticking. Lubed it & ordered a new one just in case. Working fine now. Thanks for the ideas

Thanks for the follow up...I'll keep this in mind if the same thing happens to me.
