2004 Buick Rendezvous Q&A
2004 Buick Rendezvous Question: Engine?
I have a 2004 Rendezvous, yesterday I was driving and started losing engine power going uphill, This morning I changed the oil which needed to be changed, I took it for a test drive and it seemed the problem had gone away, 1 hour later as I was driving it did it again, I could only do about 35 MPH going uphill, will this be an engine, transmission problem? or changing the air filter will solve it, Please Help!!! - eddieyelena
