ny cracked hose can cause a problem, and no you will need to clear the code once the repairs are made

The small hoses in the tee are for your cruise control. The ripped hose you have can be purchased at www.roverparts.com, but with shipping, your dealer should be about the same. Plus you get it right now...

I can tell you the your Bosch wires are junk. I threw a set on mine when I got it, not knowing any better. They were toast in less than a year, and they replaced them under warranty. I got a new set of 8MM Magnacor wires and haven't had any more troubles. Really, they are the only way to go. www.apexperformance.net has a good price for the set. If you look at your throttle body from the front of the truck, there are 2 connectors the plug wires into things. The one on the right is your IACV, and the left one is your TPS.

Google Rave download and you can download a free shop manual for your truck, or buy one on CD for $10 on E-bay...

Also, Harbor freight has a code scanner for $40 that will clear your codes. Well worth it.

ok my disco is still shaking/rumbling but not that bad but you can notice it and feel it in your seat when ideling. Now when i drive it the motor hesitates at like 1500-2000 rpms until itake my foot off of the gas and gas it it to pop past it. My question is could my problem be the coil pack because i had already replaced the plugs and wires, or fuel pump/filter, or is my problem air related is my MAF faulty? thanks

You could have a loose wire? Go push them in and see if one is loose!

Left is U.S. driver side,,, Right is U.K. driver side.

If you have a bad hose on the left side it would be after
the Mass Air Flow Sensor and that would make it run very bad.

I am in the US and the cracked hose was the one on the passanger side that goes from the valve cover to the intake mani. Would the cause my problems?
