I bet the shaking was all due to the MAF, like stallion said. I had the same problem with violent shaking and weird idle rpms, only to find that my cold-air intake cracked open on the engine side of the MAF.
Update: I have no idea what I did, but the car is running again and everything is ok and normal…going to try to install the chip 1 last time and if it doesn’t work, I’m giving up for today.
I had the same problem with my Diablo chip after I got it back after a reburn.
The car would start and then immediatly die. I disconnected the battery, pulled out the chip, cleaned off the connectors and re-installed. After that it
was ok. Twice since then I've started the car, and it would immediately die. I needed to keep revving it to keep the rpm's up and then
slowly bring them down until I could tell it wasn't going to die. I believe it
is directly related to the chip. Like I said, it's only done it twice in 4 years
so I am not sure what it was. Now that I think about it that is really bothering me. Diablo chip is coming out anyway in place of a Superchip with
Custom dyno and tune. Now I'm ramblin'.
