Default UPDATE on my Misfiring SAGA.

So I replaced the MAF to see if that was it. The car was running perfect so I thought I found the problem but after a few days it started up again and I got a CEL. Ferris VAGed it and found these codes;

16684 (P0300) Random Misfire Detected
16688 (P0304) Cylinder 4 Misfire Detected
16690 (P0306) Cylinder 6 Misfire Detected
16689 (P0305) Cylinder 5 Misfire Detected
18010 (P1602) Power Supply (B+) terminal 30 Low Voltage
INTERMITTENT
17965 (P1557)---Unknown Trouble Code
17537 (P1129)---Unknown Trouble Code
17535 (P1127) Long Term Fuel Trim Mul. System too Rich (Bank 1)INTERMITTENT

Does anyone know what might be going on with my car? What are the Trouble Codes?

Default I had a similar problem---

It was VERY mysterious as it would come and go----eventually I found a defect in the #4 plug wire that would intermittently short out and cause all sorts of problems. Replaced the lead and the problem was solved! good luck

Default Check the voltage of your alternator and check all grounds.

Try running a 4 guage ground wire from your battery to one of the bolts that holds your coil on.

Default Actually you don't always throw a code for it and yes this would be a good idea to replace

it is cheap. do you have any warm starting issues?
