So this morning im driving my son to my moms place and it starts hesitating pretty bad. Let off the gas and nice and smooth idle. Sit at a red light... nice and smooth. Take off and start sputtering and jerking again. I had about an 8 minute ride to my moms place and once I got there i put it in park and revved it up to like 3-4 and it was nice and smooth through the rev. I bring my son in and go home and its running fine. This happend last night too on the way to pick him up. I thought it was because i was riding it so close to E as I was on my way to the gas station it started doing it, but i thought cause maybe I was out of gas. then after I left the gas station it was ok.

So right now it has to be something with warming up. And its not all the time the idle was smooth and rev was smooth. It just appears to be under load. I have to do more testing so when I pick him up tonight I hope it does it so i can test more about being cold and under load conditions.

But any ideas on where to look or what might cause that is appreciated.

I'll report back with any additional info I may get tonight.

 

Id start by checking injectors/spark and than the TPS

 

ya when was your last tune up?

I'm assuming we're talking about the 4.0?
