help with an import

sorry to post about an import.. and if this needs to go to the tech section i'm sorry to have posted it here..

i searched google, and different eclipse forums w/o luck. car in question is a 99 eclipes with a 420a 2.0 4 cyl with 5 speed. problem is it's sputtering at low rpms/taking off. this is my girlfriends car and would like to fix the issue.

i did some maintenance on it today just bacause it needed it, plugs with proper gap, wires, fuel filter, and new batt(old on had a dead cell). i cleaned the sensors around the TB but not the TB itself. i also checked the coil for a good blueish/whiteish spark. no vac. leaks. ohh it once had a O2 code that was cleared with a scaner. but not replaced. there is no CEL on the dash.

i'm sure i'll end up figureing it out before long. but wanted a lil help from you guys/girls.

I am trying to remember if that is the version with the MAF integrated in the air filter canister. Is it a turbo? Definately replace the O2 sensor.

non turbo and SD from factory or non maf.

02 is on the list. ;)

bump..

any more idea's? new O2 with no change.

i dont like how this thing sputters like this.. one slip up putting out in traffic could be bad.. i did'nt know how bad it was till i drove it the other day. i really want to get this fixed. i'd rather her drive the goat then this death trap.

Could be a couple of things. Blocked cat, dirty throttle body, fuel pump on the way out. Have you used any fuel system cleaner at all?

Did you replace the cap and rotor?

TB is still a lil dirty, will try cleaning. she nor i have put in any fuel cleaner. i want to add the 2 cycle. i told her that i use it in the goat. thats all i had to say to convince her it was ok to use.

i talked with an import friend of mine who had a similar problem with a acura 4cyl 5 speed. he said it was the TPS. i already took the sensors off the TB and cleaned them, but that dont mean either one is'nt on it's way to takeing a shit.. Still no Check Engine Light.

this car has a coil pack, and has a very good blue/whiteish spark.

it sputters at low rpm/take off. >1200rpm

How many miles are on the car? Could be fuel pump/lines?

sorry.. it has 120,000 as of yesterday. always changed the oil at around 3-5k.

i'm not sure about the fuel pump. i'll look into it. btw.. the engine runs smooth, no misses, no skips. this is with out running a compresstion test, which i can do by the weekend. untill then, i'll read up on how to check the fuel pump for proper output.



**somthing to add to the list. the cam sensor has had a small oil leak for a while. i also fixed that with a new OEM gasket and cleaned the mateing surface with cleaner but did'nt clean the sensor itself. it could be jamed with oil/crap in the plug area.. giving weak signals.

ok........... spray for vaccum leaks again, AND spray around the fuel injectors, if the o rings go bad, they will leak.
