So I go down to the test only place, pay for a pre-test and everything goes good. Visual pass, tailpipe pass. Then they go do the "real" test and they said they kept getting an acceleration violation on their computer. They couldn't explain to me what that is and just shrugged their shoulders and failed me. The good thing, they didn't charge me for it. But, does anyone have an idea WTF that is???

It's when your car is being smog tested under load to simulate normal driving conditions. Passing the other two is easy and therefore, being that we all live in the great state of CA, we must now pass the new test also. Unless of course you live in a county that is exempt.

It was on the rollers for both the pre-test and actual test

the pretest is pretty similar to the real test. ive done a few at school but i have no clue what that means.

Guess I didn't really make myself clear, I'm asking what does "acceleration violation" mean in terms of a smog test failure.

never heard of it and I failed everything possible with my car on 12 pre-tests last year...

I'd try another smog place?

Read up on this. Sure looks to me it's the techs fault...

I know the guy who smoged my car real well and have seen him do mine and a few other on the dyno. The tech has to control the rpm and keep it within a certain speed or else the test won't work, pretty much just like it says in the article. I would go to a smog tech who knows what they are doing.

If I took it to a smog tech who knew what they were doing, then I'd fail the visual! [Big Grin] The place I went to today didn't even open my hood.

An "accel violation" is when the tech cant get the car to stabilize on the dyno(sometimes extra tough when the car has a lopey cam, sticky/stiff throttle operation, etc) quick enough, the machine usually gives you a few "do overs" before it kicks you out of the test. Sounds like he was able to tame the throttle on the pre-test but blew it on the real test, not much you can do, he could have run the test again but that was up to him. Your car technically didnt fail the test, it just wasnt completed. I would guess he doesnt want to try to run the car again, maybe you'll get lucky and find somebody else that wont notice the 351 under the hood. hope this helps, good luck

Yup, same thing happened to me. Kept having accel violations. The tech had to retest it about 5 times hahah, finally got it to pass. He felt that it was my different gear ratio (3.73) that made it hard for him to complete the test.
