I have a 2003 Yukon, 5.3L engine
. Been having engine light on for a few months; still trying to fix problem. Intake gasket replaced, not resolved. Just last week it started flashing as well. Took to another mechanic; they replaced fuel filter, fuel pressure relator; and one oxygen sensor. They said they drove it and it was fixed. I drove it - check engine light stilll on. I called and they said I need to replace my gas cap. I have not done that yet. As I drove it home anytime I go over 30 mph (whether in gear or in neutral) the engine light flashes. I go under 30 mph, and it goes off. It also randomly runs smooth, then a little rough. I am trying to figure out what is wrong I've paid almost $1000 to fix this and I don't have anything left to take to another mechanic.
JA: Diagnosing the correct check engine code is the key to getting a quick fix. Fortunately, the mechanics we work with have tons of experience dealing with this type of thing. Are you hoping to fix this yourself?
Customer: I am considering that. My husband has auto mechanic experience, and I am pretty handy but don't know if this is over my head.
JA: Is there anything else the Chevy Mechanic should be aware of about your Chevy?
Customer: Hmmm. It's been kind of a lemon. We bought it at 80,000 miles and have replaced tons of stuff; including transmission. This is our first enginie/fuel/spark problem though.
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the Chevy Mechanic about your situation and then connect you two.
