Total Newb needs help with DIAG

[wtfdidIgetinto]

Ok, first time ever on a forum and first dsm ever... this should be good. I bought a 91 eclipse for a grand. Drove it for months with zero issues. Boosts fine (17psi) and drove great. Recently I was driving and the car lost all power. Engine never stall but I had to limp it home. I am talking LIMP. It will free rev fine but under any load it bucks and jerks almost like fuel cut even at quarter throttle. I let it sit for a couple of days. Fires right up and rund great UNTIL it completely warms up then barely moves. I dont know where to even start with this thing. Please help. I tried searching but couldnt quite find a similar problem. Car does not overheat what so ever.

Also check your Engine coolant temp sensor

do a boost leak test or smoke test you might have a split in one of the intake hoses.

I will probably buy one tomorrow (coolant temp sensor). They are most likey pretty cheap anyway and this one now has 90k miles on it.

Could be a vacuum line leak somewhere

Yeah sounds like something a vacuum line could cause, wouldn't take much for an old line to split.
