Could a timing belt be causing my 2005 v6 sonata to be sluggish when accelerating?

SOURCE: my buddy has a 2000

Have you checked the MAF and/or TPS sensor?. I have had the same issue before on the same kind of car and it turned out to be the MAF sensor.

Size 75 was the standard battery many of the newer size 75's are actually stronger than the old 78's, so you can probably get away with a 75 which is a little smaller and lighter.

Whenever the 'CHECK ENGINE' light comes on, the ECU (Engine Control Unit) sets a Diagnostic Trouble Code (DTC). These codes identify the particular engine management system which caused the light to come on. You'll need to use/find an OBDII (On-Board Diagnostic) Scanner to retrieve any code which have been stored in the ECU computer. Afterward, we might be able to help you DIAGNOSE and perhaps eventually fix the problem.

DOES THE ENGINE MIL WARNING LIGHT COME ON? WITH OUT MORE INFO YOU NEED TO CHECK MOTOR ON A CODE READER FOR STORED FAULTS, CHECK ALL AIR LINES TO EMMISION CONTROL, , SOUNDS LIKE YOU HAVE GONE INTO SAFE MODE, A SPLIT OR LEAKING PIPE ON THE INTERCOOLER IS A COMON FAULT ON THESE, IF YOU SWITCH ENGINE OF AND BACK ON QUICKLY WITH MOTOR RUNNING WITH OUT STALLING MOTOR AND IT CLEARS THEN IT IS PROBERLY THE SAFE MODE CUTING IN MEANING A FAULT HAS BEEN SEEN BY PCM

Testimonial: "Thanks.Didn't notice any engine lights came on. I had a problem free day today, but if it happens again will check warnings and PCM computer check"
