my car goes put putt putt after it warms up. this just started yesterday for the first time. when i hit the gas teh car is real choppy and shakey. its like putt putt putt until i turn it off and let it chill for a while. the problem comes back after about a couple miles.

i do recall racing someone before the problem came, could that have anything to do with it? it was the first time i actually raced this car.

had this problem before...one time i had a vaccum hose leaking so check those. the other time my injector harness was knocked loose so check those.

 

I had that problem right before my #5 injector died! but hopefully for you it might just be the harness like Chris is saying!

 

probably somethin with the harness, mine F#cks up too and i have yet to figrue it out.. luckily it goes away after a minute of driving so it doesnt bug me enough to fix it yet..

 

when my battery was low my car putt-putted. i remember sitting there in the driver seat one day..i almost cried and said "oh no, my car is putt putting" to my friend. so after a couple months and a few jump starts i replaced the alternator...purrs fine now. i dono if it's the same putt putt, but good luck.

 

After i get the ride back i'm changing out all of the harnesses. Seems like many of us have this issue...

 

try cleaning the connectors. Pinch down the female side so that they grab the tabs better. This is probably an oxidation problem. When I pulled my injectors and installed new seals, that was one thing I did along with the job.

 

how much you gettin the harness for, and how hard do you think its gonnabe to replace it?

 

well it turns out that injector #3 is bad. so nissan is going to replace that. how much should that cost? we'll see how the car feels when it comes back.

 

haven't priced them out yet. I remember PoLo replaced his awhile back. I think the rears need to be spliced in but I think overall it's a simple wiring job.
