Rough Idle; I have done full tune up, and it got worse

[cocka]

I think that's what i'll do then. Replace the Throttle Position Sensor, and clean the throttle body itself; and just take a look at the lower engine mount - is this easy to change? I've seen the tutorial on Bay 13, but i'd like some opinions from people who have actually done it.

BTW, thanks so much for the input so far guys. I really appreciate it.

Re the lower engine mount (I take it you mean the what would be the front one on a "normal" engine), if it's u/s the engine will actually be resting on the subframe, use a bar or similar and you will be able lever it (the engine that is) up and down, tools you will need are a jack, a stand, a clamp of some kind to hold inner guard panel back, a piece of timber to go between sump and jack, 14mm & 17mm sockets (shortish/squat ones are best, not a lot room to work in) and a wheel brace.
It took me about 45/50 min to replace mine and I'm a mug mechanic, I reckon I could do it now in less than 30 min easy.

Took it to a local shop cuz i started leaking coolant. They changed the timing belt, water pump, and belt tensioner. I also had them look at the rough idling. Turns out that i had some vaccum hoses within the manifold that were cracked and broken, as well as some old O-Rings,so they replaced all that - $960.63 total.
