Hi. So after My cars warmed up the idle gets rough. Doesn't have this problem on startup. I then cleaned my maf, tb, and intake. The accordion tube that connected to the tb had a lot of gelatinous oil boogers/ tb had oil clogging the butterfly. Then I reset ecu by disconnecting the battery.

Now my car is even worse, idle now dips to 500 and car shakes more vigorously and I hear a lot of chirping noises at low rpm. Please help! I couldn't check the spark plugs yet (gf sad I spend more time on car) but is that a likely culprit?

I have just been thru hell trying to find my problem also.. It's taken me 3months.
Among all the usual suspects u can try testing ur neutral sensor switch at the top of the gearbox and also the reverse switch.. It was my culprit, damn neutral switch.. Mine was stalling always and hunting etc.. Now it's purr-fect

69k miles, 2004 mt, I've had it since September, a little after I got it I replaced the coils, spark plugs, cleaned injectors, replaced clutch, replaced cracked fuel pump.

I'll check the switch if I can. The reason I think it might be the spark plugs is because I had dirty injectors, I cleaned them after I replaced the spark plugs so I'm worried that the dirty injectors fouled up my new spark plugs.

Also it seems the longer/harder I run the car, the worse the shaking becomes...not sure what to make of it....does a bad engine mount get worse with heat?

Thanks guys

Did you also replace the wires when you did the coils and plugs ? Do you keep the oil filled up to the full line or is it overfilled ? that can lead to oil in the manifold.

I think the guy I got an oil change from overfilled it. Lesson learned, do it myself. And yes I believe the coils came with new wires.
