well lets see, today i got up went to my car and wow, it took it like 5 tries before it would start, then i notice the temp gauage isn't working, the car idols like a lawn mower, and the exhaust is all broken up sounding. OH and the damn thing is running FULL rich. And it won't rev past 3000?

SO, is it just the thernostat and the car is in safe mode, or is it more? Anyone?

 

I wouldnt run your car very long if it was running full rich. The excess gas will wash the rings out.

 

run a compression check, sounds like you lost compression in one of your cylinders.

 

what are u boosted on? is the CEL on? how do u know it's running full rich?

if it is running full rich, then ECU is in limp mode. it won't rev past 3000 because ECU is in limp mode.

could be more....can't really say...there's not too much info to go off of

 

mayb your low on oil?

 

You have to give more info..... Was the car acting up previous to that morning? Do you have any CEL's? What kind of engine management system do you have? I am assuming you are turbo from your your name 'boosted_K20'.

here is a list of what you should do
1. pull the dipstick and check the oil, note the condition and the level
2. If you have CEL on scan the ECU and get the code(s).
3. If you have access to a honda scanner (or similarly capable scanner) you can monitor the running parameters of the motor to see what is not doing what it should (e.g. fuel ratio, engine temp, idle, fuel press,etc....anything the ECU sees)
4. Do a quick physical exam of the motor and turbo making sure all vaccuum lines are connected, sensors plugged in, any physical damage to the motor or turbo.
5. If all checks out then do a compression test and leak down
6. if all else fails pay someone to fix it.
