Is the MIL (check engine light/malfunction indicator lamp) on?Our '02 Camry "chugs" down the street. Whether you are going 25 mph or 65 mph, it constantly feels like you are pushing in and out on the gas peddle. Help, what should we do? Has anyone else had this problem?
Welcome to TN.No check engine light. We just had the 90K service done in December too.
Most (if not all) of those things would cause the MIL to come on and store a code (usually a miss fire code). The OP stated that the MIL is not on. Checking for a miss when there isn't a miss fire code really isn't the best way to perform a diagnosis. It's doubtful that the timing belt was installed incorrectly and then decided to act up 2 months later.Did you get the tiiming belt changed recently? If so then the mechanic screwed up the install and needs to reinstall the belt.
Other things that might cause this:
-timing belt worn and stretched, has skipped a couple of teeth i.e. it has jumped time
-timing belt tensioner worn out and not applying pressure to idler, and timing belt is too loose and has jumped time because of that
-One or more injectors clogged or dead (i had this happen on another car and it also idled poorly too, but did not even throw a code)
-weak fuel pump (but usually a fuel pump just quits working and does not do a slow fade)
-one or more spark plugs not firing (but usually this would make the CEL blink on)
-one or more dead coil packs (the big plastic and rubber thing that fits over the spark plug)
-low engine compression and needs a valve job or more
-a transmission issue
