Long story short,last year my motor locked up,no oil to camshaft journal.got a new head installed all new brian crower products. Cams,Valves,retainers.bottom end is a stock.
Finally got the car running,but between 1500-2000rpm car bucks/jerks,so bad that i gotta floor it or let off the gas.Makes it tough driving through the city,now on the highway it drives like a champ!
could it be the cam degree isnt set right? needs tuning? any suggestions will be greatly appreciated!

what cams did u install? might need a tune, definitely not the degree of the cam, what ecu is in the car now? any check engine lights?

I installed the BC stage 2 naturally aspirated cams (BC0012).as of now its running on stock b16 ecu (OBD1)
and CEL for 02 sensor.

you need a tune and get that o2 sensor

Out of curiosity what could be so out of range where it would cause to jerk like that so bad?
air/fuel maps?
and any good tuners around the nova area? if not ill be trailering it to shue or possibly up north
thanks for the help drag!

you need better vtech fluid

well there is one of your problems, your running aftermarket cams on a stock ecu. i would
really get a good tune on it before driving it any more then you have to.

If i were you i would take it to shue, the guy is amazing at tuning work.

VTECH fluid,already tryed that..didnt work =[

and shue will most likely be the tuner,havent heard anything negative about the man..

You need to fix the O2 sensor problem and get tuned for those cams. O2 sensor failure can be a strange thing and could definitely cause problems like you're talking about if the sensor is going out of its normal range. In that case, who knows what the ECU is doing to handle that. It should be done fairly gracefully, but if the sensor suddenly changes values and the ECU is going to a faraway spot on one of the maps, who knows...

Anyway though, you know you need a tune, and you know you have an O2 sensor problem. Fix the O2 sensor first, then reset the ECU and see how everything behaves. Then go get tuned when you're able.
