im having issues with my eclipse its a 94 1.8 sohc. and when the car is at idle it idles fine for about 5 or 6 mins then drops down to around 600 to 500rpms and begins running really ruff. Then when you accelerate. and stop again it does the same thing also other times it will just die out while driving. I checked all the vacuum lines and thought it might be one of those. But it doesnt look like any of them are disconnected. I was talking it over with one of my friends and he said it could just need a new cap and rotor,and maybe a new set of plugs and wires as well. could it just need a tune up?? or could it be somthing more serious

o the car is an auto with over drive and has around 145k on the motor

 

i've been having somewhat of the same problem with my 98 rs and i pumped the gas because the rpms were dropping while i was in 5th gear then i downshifted and pumped the gas again and then the rpms jumped and the car ran fine. the car kept giving me problems and wouldn't start. it was would turn over and that was it. i bought a new batter and had the rest of the charging system checked and it still did it. i talked to my friend and he was telling me to check my ecu connections. i disconnected and reconnected it and it starts fine and hasn't died out since.

 

hmm ill have to try that becasue for the moment im without a car

 

it might just be that your mass air flow sensor is dirty. go get mass airflow sensor cleaner for like 5$. make sure that it's mass air flow cleaner and not throttle body cleaner.

 

i put a new air intake on there a couple of weeks back could that be the problem. but then again it was still dieing out with the stock intake on it

 

tried cleaning it and reconnecting the ecu still dieing out any other ideas
