Freelander Stalling: TPS Problem or Something Else?

Hey there! I have some experience working on cars and faced something really similar with my 2005 Land Rover Discovery (2.0L petrol). The symptoms were almost identical to what you're describing with your Freelander. Mine turned out to be a faulty throttle body, specifically the internal mechanics were shot. Got it fixed at my regular workshop, and it set me back about 345 Euro. The repair made a huge difference, all the jerking and rough running disappeared completely. Could definitely be the same issue on your Freelander since they share similar components with the Discovery. But to help you better, have you scanned for error codes? Does it happen more when the engine is cold or warm? Any recent work done on the car? Let me know these details and I can share more specific advice from my experience!

Thanks for sharing your experience! I had my last service about 3 weeks ago at 108,694 km, and yep, I've got the error codes scanned. It's definitely happening more when the engine is warm, usually after about 15-20 minutes of driving. The mechanic cleaned the throttle body during my recent service, but the problem came back pretty quickly. I'm thinking your Discovery issue might be pretty close to what I'm dealing with. Really helpful to know about the throttle body fix, might save me some time diagnosing. Would you recommend replacing the whole unit or trying to clean it again first?

Hey again! Since we have pretty similar cars, let me share more about my experience. After I first noticed these issues on my Discovery, I actually tried cleaning the throttle body twice before going for a replacement. The cleaning would help for maybe a week or two, but then all the symptoms would come creeping back, especially that annoying jerking during acceleration. The fact that your problems are worse when the engine's warm is exactly what I experienced too. In my case, it turned out the internal components of the throttle body were wearing out, which is why cleaning only helped temporarily. Trust me, I tried to avoid the full replacement cost, but in the end, it was just postponing the inevitable. Given that your symptoms came back so quickly after cleaning, I'd honestly recommend just going for the full replacement. It'll save you money in the long run, I wasted about 100 Euro on repeated cleaning attempts before finally replacing it. Plus, the poor fuel economy alone probably cost me more than the repair would have! If you want to be extra sure before spending the money, try checking if there's any carbon build-up visible around the butterfly valve. That's what convinced me it was time for a replacement, you could barely see the original metal through all the gunk, even right after cleaning!

Thanks so much for all that detailed info! Really appreciate you taking the time to explain your experience. You've actually convinced me to bite the bullet and go for the full throttle body replacement, seems pointless to keep throwing money at cleaning when it's just a temporary fix. That carbon build-up tip was super helpful too. I just checked mine and wow... it's pretty nasty in there! Definitely explains the poor performance. I'll give my mechanic a call tomorrow and get it sorted. Thanks again for saving me from the whole trial-and-error phase you went through. Fingers crossed this fixes it once and for all!
