I have a 2001 rodeo 6cyl that runs rough and even kills at idle. When I step on the gas the cehck engine lite flashes and quits when I release. Anybody got any ideas?

if you have a flashing CEL it means there is a miss fire.

Autozone will read the codes for free.

the number 1 cause for this on +98 Zu's is a bad intake manifold gasket.

if you are the 1st owner it is covered for 10yr 120k.

Amigo-2k,

Thank You for the info. It sure is great to have people take the time to assit others without expecting something in return. Your a gooe person.

Het Amigo-2k,

Is this why it whistles sometimes also?

yes, its whistling because there is a little hole in the gasket and air is being sucked in.... giving that whistling sound.

The oxygen sensors are telling the computer that the engine is not getting enough gasoline (because of the extra unmetered air beign sucked in) and so gives an error code for a lean mixture.

Not really a misfire, but a lean code would pop up. I spose you could get a misfire code if it ran with a bad gasket long enough, since the computer is dumping in extra gasoline from the lean reading.

Isuzu mechanics can fix the gasket in around 30 minutes. Theyve done it a Zillion times.

Our 2000 Rodeo does this also. CEL was read by the dealership as a bad MAF sensor. I still think it is the IMG though, but these were replaced a year ago!? :roll:
