Default Long Term Trim -20 both banks

2008 XKR running rich with long term trim averaging -20 causing P072 and P075 setting off check engine light. Replaced upstream O2 sensors, maf sensors, plugs, cleaned airfilters and changed nothing. I have aftermarket airfilters which shortens the tube to the filter to about 18 inches and was told by one mechanic that I needed the stock system. Anyone seen this before and have any ideas? Thx, Ron

Welcome to the forums Ron,

I've moved your question from General Tech Help to X150 forum. This is the place to post technical questions about your model.

Please follow this link New Member Area - Intro a MUST - Jaguar Forums - Jaguar Enthusiasts Forum to the New Member Area - Intro a MUST forum and post some information about yourself and your vehicle for all members to see. In return you'll get a proper welcome and some useful advice about posting to the forum.

Good advice from that mechanic. The OEM Genuine Jaguar engine air filters are sold in a matched set of 2. Using aftermarket filters is a crapshoot.

Read Brutal's Post #8, here: https://www.jaguarforums.com/forum/x...esolved-92749/

Welcome to the Forum, Ron. There are many helpful and knowledgeable members here and a great Advanced Search function to help you find the answers to most of your questions. For example, it took me less than a minute to find Brutal's post. Be sure to browse through the "Stickies" at the top of this Forum's Home Page and create a signature that includes your model year and any other information that you want to share. Post some pics! I hope you enjoy your XKR as much as I enjoy mine!
Stuart

Can you post some photos please of what after market intake setup that you have here? Also did you replace maf with
DENSO brand or something else?

The filter system is from Mina Galleries and this picture represents what it looks like with one feeding the left and the other feeding the right. The MAF sensors that I installed were Jaguar OEM. Thanks for your interest. Ron

Did you ever do a Hard Reset after your mods? If you haven't, the car still wants to drive on it's initial 'learn' and is trying to make that work right.
