I have a 2000 S type Jaguar with a 3.0 and runs ok at idle but rear rough after gets hot and has no chek engine light on or any codes. Has been sitting for a while. Has a used fuel pump and a used transmission. Engine will not go above 3000 rpm, trans has delay going into gear. Engine cuts out bad and sounds like it back fires sometimes. Feels like it is losing throttle control or hitting the rpm limiter.

SOURCE: car is boging out in park and will not go over

The engine will not free rev at 3000 rpm - its self protecting.
I do not understand what ''boging out '' means so can not help with this part of the question.
good luck

fail safe mode is something the vehicle computor will go into when there is a problem with the vehicle it allows u to get off the highway or road safely you need to take vehicle to repair shop or your dealer which ever u prefer Failsafe engine mode on a 2000 jaguar s type is caused by a stopped up throttle body. Jaguar says not to clean the throttle body since it has a protective coating to help keep deposits from accumulating. You can clean the throttle body as long as you use ONLY throttle body cleaner that states it is safe to use with a protective coating. The butterfly valve in the throttle body will actually stick not allowing air to flow into the manifold causing failsafe engine mode to kick in reducing the amount of power your engine will produce. To solve the issue just clean out your throttle body, it will cost you around $5 dollars and take 1 hour of your time.
