so im driving today and all the sudden a cel pops on. the car is still driving fine but i have a cel. when i got home i ran my scanner and got these codes

p0100- maf or vaf malfunction
p0101- maf or vaf circuit range performance
p0103- maf or vaf circuit high input
p0200- injector circuit open
p0372- timing reference high resistance signal, too few pulses
p1371- manufacturer control ignition system or misfire

at idle the rpms jump up to 1500 every few minutes other then that the car is ok but not running like it should be

A laundry list of trouble codes is a good indication of bad battery contacts/cables or grounds. Check out whatever you can find.

you may as well check the other engine grounds, at alt bracket/wp stud iirc and theres a small strap rear of drivers side head to firewall.

ok i checked all grounds and especially the g104 ground re tightened everything. i started up the car and the cel went off. if it stays off then this was the problem but if it isn't what could cause all those codes
