• Poor idle or hesitation
• No throttle response
• Position-sensor correlation fault
• Carbon build-up or sticking plate

🛠️ Service Notes

• Clean both mating faces down to bare metal and remove every trace of the old gasket without scoring or dishing the surface — a scraped or filed sealing face will not seal reliably again
• Fit new gaskets, seals and O-rings, and use only the sealant the manual specifies and only where it specifies it; surplus sealant squeezes into the coolant passages and blocks them
• Check that the internal passages and threaded ports of the new body are clear and undamaged before it goes on, and transfer sensors, plugs and fittings across with new seals
• Tighten the fasteners evenly, in the sequence and to the figures in the workshop manual for your engine — these are light castings and will distort or crack if pulled down unevenly
• Refill and bleed the cooling system, then check for leaks with the engine warm and the system up to pressure
