Here is the entire story from when I got the car and what it is doing now. I bought this clean 99 GT and there was a minor low rpm misfire but that was the only thing wrong. Well it has just got a little worse I think. It is sputtering and hesitating in low rpm's from 1k to 2k rpm's and is more evident under heavier acceleration. Then above 2k rpm's the car seems to run fine and I cannot notice the miss.
So the other day I took my Predator tuner and removed the diablo tune and set it to factory backup.. I then tried adding some seafoam to the vacumm hose on the rubber intake that connects to the upper metal intake and realized it did not have enough vacumm. I filled the car up with premium gas also and it seems to be doing worse. I then re-installed the diablo tune and removed the EGR valve in custom tuning. I then cleaned the MAF with electrical cleaner.
The car is still sputtering and there are no CEL on. The only code it reads is p1000, not sure what it is. The car has 100k on it and has the following mods in the signature. Has anyone else encountered this low rpm miss and how can I fix it. i am really frustrated with it. Thanks in advance!
