The car is a 91 crx dx with a b16. Ive had the engine for about a year now, with no problems till now. Ive had the car in the local shop for about 2 weeks now, and they cant seem to figure it out. Once the car warms up, it will stutter pretty bad throughout the entire rpm range. When i have it at about 1/8 throttle, it doesn't stutter.
Here is a vid. i found: http://www.youtube.com/watch?v=j8t0tud1Qh8
At the beginning, you notice that the car stutters. Thats exactly what mine is doing throughout the entire rpm range. But, the major difference from the vid. and my car is that i don't have a turbo. Any help would be appreciated.

 

Um, any codes? TPS adjusted properly? Have you checked your fuel pressure? Compression test?

I.E. this could be a lot of problems. What has been checked already?

 

Fuel pressure needs to be checked. My hatch will do that if the fuel pressure is too low.

 

no codes, going down to the shop right now to pick it up. I'll keep those questions in mind when i talk to them.

Edit: they found the problem right as i got there. Seems that the ecu pins where bad and the contacts where not touching at some point. Weard huh?

I had the same problem...mine ended up being the distributor

 

sounds like a Dizzy or a Map sensor problem.
