Toyota MR2 Message Board - View Single Post - 98 Beams MR2 Hard to start when engine warm

Hi,
I recently purchased a 98 Beams MR2 with the clutch gone. I replaced the clutch and started using the car to find an erratic idle issue, high/low revs @ idlle and stalling at junctions.

I bled the system with the two hoses attached. At the same time cleaned the two sensors/switches that are mounted on the intake (beside the butterfly).

Unsure which one of these cured my idle problem but hey its cured, now idles perfect.

My problem now is that after the car is turned off after any type of journey the car doesnt start right:

eg: Go to work 7:30am - start car at 10:00am to find car turning over slightly slower than norm but not even tyring to fire. Car will then start after about 10 - 20 sceconds turning over.
This same thing happens after 20mins cooling after a journey.

When the car is left over night it starts first turn.

Car is suffering no other issues apart from possible battery drain after 2weeks of not being used.

I have checked fuel lines to find nothing exposed to exhaust heat.
ECU light never been an issue either.
Jumpered the diagnostic port at TC E1 to find nothing stored.

Any help or advice given will be much appreciated.

Thanks,
Jon.
