Hi, I read up on how to do compression tests they all require removing spark plugs/coil packs from ALL cylinders. Could you help me understand why it is required to remove ALL spark plugs/coil packs? I am asking because it is painful to remove them on the bank 1 and my current issue is...

Is there any way to test a gas cap to see if it is the cause of the evap check engine code? Is the cap supposed to seal the system airtight? I don't want to just go buy another one if I don't need it, besides, we're pretty far from the parts store. Thanks

My 2003 Sienna went for a sensor clean/check in a shop before I the smog check, the mechanic reset the computer, then after driving it for 80 miles in about 3 days I did take the car for the smog test. The emission test report shows smog passed but Catalyst is Not Ready, this prevented the...

I have a 2005 Toyota Sienna. The a/c clutch is not engaging. The relay is good and getting power. I have jumped the contacts at the relay and still nothing. I want to check power at the clutch, but not sure what cable is providing power. Can someone tell me where the cable connection is located...

We test-drove a new LE and an SE back to back and noticed a few differences from our '13 LE fwd with 58K on it.The new LE felt a lot tighter in the handling department than our '13 LE. And of course, the display was a lot nicer, including the backup camera. The new SE felt a lot heavier as far...

On a recent Jay Leno's garage there was a 15 minute video of Carbon Revolution wheels on a 911 at Willow Springs. In the same size, CF reduced wheel weight by 5 pounds each wheel over forged alloy. This reduces unsprung weight (better ride, road contact) and reduced rotational mass (better...

Hello to all! I am helping a family member with their 2005 Toyota Sienna XLE 3.3 V6, (120.000 miles) and i wanted to know how and where i can check the fuel pressure. In the last 6 months the van started doing all this weird things... *Running rough (rpm was low around 3-400) *Check engine...

Does anyone have the exact drive cycle steps for a 2007 sienna? I have searched and have only been able to find general info in which I've tried to get the evap monitor to complete but I've not been successful so I figure that perhaps the exact drive cycle would help me in getting that monitor...

When one reads spark plug reviews, people say the engine runs better with new plugs. While some of that could be due to better gap in new plugs, I'm afraid some of that is placebo, like better running engine after oil change. Now, I understand that one can measure firing voltage via...

Hi, first post on site. Looking for a Sienna for my daughter and found a 2004 XLE with 141k and very clean for its age, one owner vehicle. I am going to have mechanic check it over if I pull the trigger, but did notice a significant amount of liquid dripping under passenger side, which I think...

Used engine on stand in my garage. Want to do a compression test. Tried spinning with impact and no luck. Starter is still on. Tried energizing starter and it spins but does not engage the fly wheel ( thinking the gear does not slide forward to engage)??? is there a safety or something that I am...

02 Sienna, 111,000 miles, oil pressure light is on and CEL P1354 (vvt mulfunction), P0300 (random multi misfires). Removed the oil pressure switch and installed an oil pressure gauge. Here is the pressure test result. Engine start: ~80 psi Idle for 20 minutes: 20 psi At 2000-3000rpm: < 40 psi...
