sounds like it's in failsafe mode. light on? is the mass airflow meter clean?? even if it's clean could be failing just not enough to set a code just cause drivebality issues, is there any codes?

no lights. the mass airflow is the only thing I have not changed - but I did take it off and clean it. I also understand it could be a comp issue. Airflo will be here thur. hope it works....... Real frustrated with no codes

Do you have a scanner that you can do data display on??

I have access to a reader but there are no codes or check engine lights. Yet each time it starts fine, step on the gas and it sputters. Let it off it idles fine. Step real soft you can get up tp about 2800rpms. All in all I am going nuts...

yes but can you explain why even when i can get the rpms up it runs fine. it just does not have the vrooom. there seems to be no miss. it sputters if gas is pushed normal or fast. but if pushed rea slow, it won't go...

sounds like a mass airflow meter even when they're failing they won't set a code until they've completely failed.
