Can anyone help me trouble shoot... I have 99 a4 1.8t. Recently I replaced innercooler with front mount and car hasnt been running correct since. Obviously i thought it was a leak in the piping somewhere. After re-inspection of all hose clamps and connections and pretty much re doing all piping i still had issues so i took it back off and put stock back on, still nothing......The car barely starts and when it does it idles rough at about 500 rpm. I tried driving around block and the car starts to go until about 3000 rpm the stalls the gets quick spurt of power then stalls again. I replaced the sparkplugs thinking it was misfiring, again no change. Then i drained gas tank and put fresh gas and octane booster, tomorrow im changing fuel filter and go from there. Any one have same issue or maybe help???? Thanks
