Hey Guys

my Girl has a 1999 Amego 6 cyl with 68K miles and last week the dreaded check engine light came on.. the ideal will not hold steady when she's cold (ie it jumps a bit ) and now when she tries to place the truck in gear (automatic) the truck stalls -

I plan to ask the folks at Autozone to trobleshoot the problem with their OBD

any ideas what could be causeing this?

Thanks
Steve

let us know what the trouble code is before buying parts it may save you some $$$$
sounds like typical EGR conern nothing major

Thanks 2eyefishclaw,

well we went and the car had seven codes the guy reccomened that we change the spark plugs (got five done the last one by the brakes seems to be a real pia)

well it runs smoother BUT it still stalls when she is warm after driving a while (just after start-up)

sorry but i don't understand what you mean by a simple EGR problem

Thanks again for all your help!

Best

Bass- make sure you have either NGK or denso spark plugs in there. Like 2eye says, could be the EGR valve is stuck open, dumping too much exhaust into the intake at idle. Could also be a bad intake manifold gasket as well- this is VERY common with 1998+ 3.2/3.5's.
G/luck!

yup we used NGK plugs

any idea where i can locate the EGR value?? and is it pretty simple to change? ok a little more reading and i beleive i have to remove the air filter tube that goes to the intake and clean the intake with some carb cleaner.. does this sound right? I am going to buy a shop manual tonight

Thanks again!!

As for the stalling when putting it into gear. I used to have a 78 Chevy custom that did that and it turned out to be too much tranny fluid. Simple enough but it confused the hell outta me for the longest time.

NO POINT IN CHANGING THE VALVE IT CAN BE CLEWANED

 

[Bass]

yes but HOW do i clean it???? - game plan is to remove the airfilter box and spray the throttle body with carb cleaner but where the heck is the egr valve

 

[JTK]

Bass, the EGR valve is at the rear left-hand corner of the intake manifold. It's cylindrical shaped can (soleniod valve) about 1.5" in diameter & 2-3" long. You unplug it, unbolt it & pull it up & out of it's mount that's cast into the intake manifold. You'll see a 3/8" stainless steel tube that runs from the left hand exhaust manifold to the EGR base. Thats the feed tube. The EGR port inside the intake is several inches insite the intake, behind the throttle plate.

AWESOME PICTURES

Thank you very much everyone I'll report back once i clean the egr

 

[Bass]

cleaned the egr and sprayed the heck out of the egr tube - still seems rough - she says it feels better today but i think it's because we have a warm day today

Thanks for all your help

Bass,
Go easy on the carb cleaner, as some brands are hell on the O2 sensor.
Good luck
