Rav, in the '95 models the starter (immobilization) relay is not in the fuse box. In '95 models built in 1994, the relay is behind the driver's side speaker grille in the footwell. In '95 models...

A bad IAC shouldn't produce a 1221 code, since the air that passes through it is metered.

It can't be the resistor because it's out of the circuit when the blower is at max. I wonder if the K4 blower relay is failing when the motor is drawing maximum power. Next time it stops working, I'd...

I've been using Zerex G-05 for years. It's pretty close to G-48 (BMW coolant) with the same HOAT chemistry, and much more widely available. That said, you can order G-48 from O'Reilly if you're able...

Absolutely. A lean condition can produce a 1221 code. There's only one sensor, BTW.

So you work in a garage? I'm sympathetic about letting things go a bit, then. I imagine it's hard to get...

I agree with everybody else that the first thing to rule out is a vacuum leak. 507 suggested a smoke test, but most big-box car parts stores will lend you a vacuum gauge through their borrow-a-tool...

So you've had this car for three years, it's always idled like crap cold, and you just noticed that it has an intake hose that's all cracked. I'll channel CapBMW here and say, WTF? Fix your car, man.

Yeah, 1990 and Canadian ... I'm not sure either. Worth a try.

Have you changed the oxygen sensor in the last 50K miles? It should throw a check-engine light if it's out of spec, but it requires...

So you have two fresh calipers up front and one of them is not getting fluid? If so, I like RAV31's suspicion about a bad brake hose. They are cheap; do all four if they look old.

They can be a...

1000 rpm is too high. It should be more like 750. You could have a couple things going on. I'd run the checks I mentioned to start. I'm not sure if you can do the "stomp test" on your car, but if you...

OK, next question: How rough is it? The M20 engine I've worked on always sounds a bit "cammy" but RPMs remain steady. Does your engine want to stall at idle, does the idle hunt or bounce? What have...

I'd check three things. Use an ohmmeter to test resistance of the coolant temperature sensor. It should be about 5900 ohms at 0 degrees C, 3800 ohms at 10 degrees and 2500 ohms at 20 degrees. If...

I would have been tempted to reseal the valley pan while I had the intake and the tubes out. The steel bolts and aluminum block can produce galvanic corrosion when they're exposed to coolant. Once...

My 540i has 270,000 miles (190,000 of them are mine). It's showing the miles cosmetically, but I'd drive it anywhere.

You'd be surprised. I've pulled a couple of dead mice out of the plenum, and the car is driven pretty much every day.

That looks like it should work.

If you plan to replace that O-ring that seals the amber cover, I think I have a couple spares -- 40mm x 2 mm. It's an odd size for an O-ring.
