Engine was running fine, but now skips at about 1500 RPM while holding accelerator steady and also while driving under load. Getting code 1391. I replaced the cam sensor and the crank sensor but that didn't solve the problems. Any ideas?

 

My 99 does the same thing. But sometimes it cuts out, and stalls. I replaced the IAC (idle Air control) and still does same thing.

 

I replaced the camshaft sensor and it cleared up my problem.
