Hi David,
Hehe, yeah thats what I thought too....But the timing chain was replaced the
first time by the dealer. At around 110,000 miles, it started having
strange symptoms, it ran really rough, missing on the first cylinder. The
first time this happened I took it to autozone and had them read the codes.
Codes PO108, PO112, PO301, and PO320 came up (Map sensor voltage too high,
air intake sensor voltage too low, cylinder 1 misfire, and No crank
reference signal at PCM were the descriptions). All of the actual sensors
tested fine according to the dealership, however, and they (Dodge) said it
was the timing chain that went bad somehow.. So I had a new timing chain
put in it and it was back to running like normal.
Unfortunately, now at 160,000 miles, the same symptoms and error codes are
occurring. This is why I think it is the timing chain--similarity of
symptoms to the first timing chain replacement. I live a few states away
from the place that did the first timing chain replacement or I would take
it back to them and let them fix it...it shouldn't be going out again so
soon. In lew of having yet another dealership do the work and charge me
500.00, I thought I might take a crack at it provided it is doable by
someone of moderate mechanical ability. :)
As for the engine, I don't think I have confused it with the 2.5 L OHC, but
I could be wrong...My dakota is a 1998 4-cylinder 2.5L engine...is there a
way to confirm whether or not it might be the OHC engine? I am open to
suggestions on what else to check, if anyone has any other ideas or
suggestions. Thanks.
