1988 Bonneville

Sirs,
I'm noticing that when my car is stitting with the engine running (no moving) the "check engine' light will come on. I don't think it's over heating. Also while driving I can hear a rumble cming from the right front wheel. (maybe the shocks?)
Any help would be great.

When the SES comes on does it idle surge or anything ,got to be more specific.
Rumbling could be wheel bearing,seems to be common.

Get the car scanned, as that will tell you the cause of the check engine light. The rumble while driving is most likely a hub bearing.

the check engine light was due to a problem with the EGR Flow. Put some Sea Foam in the car and it cleaned out the mechanism. The light went bye-byes.
Thanks.
