Hi guys,
it is more than 10 years that I read with great interest this forum.... and allways I have found solutions to my problems only using the magic button... "SEARCH".

But there is always the first time for everything.....

I customer have a C5 Corvette with 383 rotating assembly, Edelbrock heads and unknow camshaft...... with Harrop Hurricane ITB intake.
The car wasn't running because the drive by wire was always in error.

Now, after some research, I have found (and solved) a problem with TPS mounting tab and spring loaded leverism. The car idles, run and drive nearly well..... at least to start to do some serious datalogging to tune the engine.

The big problem is that after few minutes of driving the engine go in limp mode with C1278 and P1514 erros.

My feeling is that the problem is coming from ABS because you can keep revving the engine in the garage for the whole afternoon.

Any suggestion ?
Anyone with Harrop ITB installed with succes ?

Thanks a lot from an Italian guy
