Low RPM & Oil Pressure at Idle

[jongreenway]

My 1997 Eclipse GST was in an accident and was now fixed but soemtimes it idles around 600 rpm and engine struggles when idled. Oil pressure drops real low as well. Help?

oil pressure will be low at idle until like 3k rpm or so. You might want to check for vacume leaks for the low idle. What is you facotry boost guage reading at idle?

It is very very very low at idle. The turbo gauge is normal.

RPM's are low at 600, they should be 900, correct?

Boost will sit half way between bottom line and 1/4 at normal, but when I have the problem it dips to just above the bottom line and then the engine starts to struggle idling.

it should be around 750prm. Thats the factory idle, but you boost guage at idle should show -14 vacume. If its like -7 or so then you have a vacume leak.

My oil guage was roughly the width of 1-1/2 needles from the bottom when at idle, stock guages arent that accurate so I wouldnt worry too much about it, I would also check oil level just to verify that there is enough oil in the engine.
