Good luck, BK
good luck
Last night - the van would crank - lights would be on full - but the engine would not fully start. I verified my batteries were OK by starting with all lights on ... thru a process of elimination - and this board - I was able to diagnose that I have a dirty IAC valve.
I knew I had strong batteries since mine were only 2-3 years old - and my EGR valve was fairly new (once replaced as part of a recall, the other - on my own dime).
I also have a new MAF sensor and new coolant PCU assembly. These were all replaced over the last two years - some as recent as 6 months ago.
I took out the IAC valve - a simple 5-10 minute process with the right tools - and cleaned it with acetone (or better yet - use carb cleaner). It was sooty and had significant carbon buildup.
Once clean and dry - I put it back on - and now, the van starts normally now.
Thanks for all the previous tips!
I would like any recommendations on troubleshooting. Both keys have been checked and work, so I suspect the van. I've made sure the steering wheel is properly seated, door locks are not stuck, gearshift is seated, etc. I do not know what fuses need to be checked for corrosion, etc. All appear to be good, just don't know which fuses work the immobilizer circuit. Any suggestions are greatly appreciated. Thanks, Rick
We have noticed engine vibration when our 2003 MPV (158k kms or ~ 100k miles) is idling at traffic lights or at the parking lot. Vibration would get stronger with longer idling time and the whole van will be shaking.
Took it to the local Canadian Tire store (we are from London, Ontario, Canada) and the techs could not read any codes from the van's computer. Either the van's computer is not working properly or the sensors are not sending out any fault codes.
They replaced the spark plugs and did the engine flush, but the vibration is still there and the tech can feel it while driving. Now they think that the pulley (where timing belt is) is cracked and is going to replace the pulley and the sensor behind the pulley. They are not sure whether this will solve the problem.
Because they cannot read the codes, they are guessing and changing parts they think causing the vibration problem. I did the engine tune up only last month and hence not sure what is the real cause of the vibration issue.
Any help you can provide will be greatly appreciated.
Thanks so much,
Sridhar.

If you've never replaced, may be worth giving it a try. It has been a bit of sore spot with MPV owners. I replaced mine a couple years ago.
or something else i can check?
