bucking bad

[tommyturbo]

Ok, so sure this has something to do with the previous problems I have been having. it's an 89. Car has 105K. Car has new cam/crank sensors, dis, coil pack, plugs and wires, 02 sensors....and wiring totally gone through. Car sets code 19 every time it is driven, and lately 49.
Today it started bucking really bad, under light load on the freeway and sometimes under load too...thought I was going to go through the windshield a few times. This is driving me nuts, and nothing seems to cure the problems this car has. Ran perfect for the first month or so I had it last year, and then has been **** since.

Try cleaning the MAF and you may want to try swapping out to a known good CCRM. The 19 code suggests a CCRM issue for me.

It's also possible that you have a bad plug or plug wire as I've seen both cause severe bucking even after a ton of maintenance was done.

how old is the fuel pump?, how much fuel pressure do you have?, did you clean your mass

As far as I know the fuel pump is original, I have never changed it. The pressure was ok when it was checked sometime ago, when I replaced the pressure regulator that was bad.

The mass air was cleaned when all the plugs/wires were done.

The CCRM, I'm not totally up on what this part does or is, can you tell me more? all my code 19 research has to do with the stuff i have gone through.

Check the codes and my guess is it's a Vehicle Speed Sensor.
