I have a 1998 Olds intrigue with a SII 3800 around 110,000 miles, and when at idle it has a slight misfire, and when you give it too much gas (only way to go without noticeable misfire is to baby it up to speed) it jerks a lot and almost sounds like its popping
. I have swapped MAF, and TPS and have looked at plugs and wires (they look fairly new). The SES light is on (and blinks sometimes when driving and misfire is bad) the codes are: slight misfire and lean bank 1 (code P1071). I also did not notice any warpage of the intake, and it doesnt leak any coolant. This is my wifes car and I need it to be running better. Any help would be apreciated, thanks in advane, Blake.
