Ok here is my story. I had a stock 5.0 with E cam and ported heads with Victor 5.0 upper and lower 75 mm tb and 42 lb injectors with matching MAF sensor. It surged up and down and most of the time it died. I idled it up to around 1200 and I didnt seem to have as much of a problem. Now that I bought the 347 and got it running its doing the same thing. Ive got fuel pressure at 43 psi and timing at 12 degrees. Is the normal fix in the IAC or TPS sensor??? Or is it something in the computer with the modifications causing it?
