Have had the camshaft in the car for about 200 miles and no mechanical problems, so its time to sort my other glitches out.


I now have a little stumble/slag at the crack of the throttle, and under heavy peddle, it will surge(once in a while, not all the time). Almost every sensor on the car has been replaced in the last year, what was not replaced has been tested, and adjusted if possible. Ignition is almost all brand new as well(have a set of mis-matched wires on it). So I'm thinking I have to much fuel cause also once in a while it will smoke out the exhaust.

Do we think 18.55 is to much for a 3.4, headers, cam, polished intake?

I see bosch makes some 18.1 lb, how about then?

Think I should go back to stock 17's and shim the regulator?

When it does run right, holy crap

 

I think that if you just go back to the stock 17lb injectors you should be fine. With the mods that you have added to the 3.4L, it's not actually taking in that much more fuel, and the small adjustments will be made by the ECM anyway. I think your best bet would be to go back to the 17's and do a little ECM flashing.

 

there lies the problem. I got the moates G3 adapter, but nobody to make me a chip.

 

id say go back to the 17s also dale. weve got a very similar setup and people behind me at a stop light can tell im running a lil on the rich side, lol. my fiance was behind me once and she called me just to tell me my car stinks like gas, lol.

 

Ok, just data logged it. Running rich almost all the time, and my block learn n something else are almost always in the red.

Time to find some bosch 17'lbs

Anyone wants to see the logs, let me know and I be happy to post them.

 

dale what size injectors do u have i have a set of 17#'s in my 2.8 right now but there to small

 

I went and found a set of 17's, but I question one.


I have 7 ford 19lbs, and I have 6 18.55lb buick/bosch injectors.
