Question about Cars & Trucks
Often while driving the rpm will drop for a moment and then shoot back up, the van is then jerking, other times the stop light comes on. I replace the thermostat and water.The system was bled and seems ok now but the jerking still occurs now and then

It sounds like you have a bad MAF (Mass Airflow Sensor). This is in your air inlet tube, pull this out and check to see if there is any corrosion on it. If is one that has a coiled exposed wire, then ensure that the wire is not broke.

Change the oil! The 318Cu in V8 (5.2 liter) engine has a problem with sludge build up on the oil pump pickup tube screen. This engine requires oil changes at or before 3500 miles with a high detergent oil.

Remove and raise upper hose at thermostat end and remove lower rad hose.
Fill rad with a hose and watch for flow from bottom rad hose and/ or bottom rad hose connecton.......water should fall though rad easily.
Honda rads are cheap.....any restriction....replace rad.
Remove thermostat....fill thermostat housing with hose and watch for water flow at bottom rad hose.
Remove heater hoses.......flush back and forth until a good flow is present "With heater control set to hot" if no or poor flow....replace heater core.
Stop leak can plug everything.
Also.......not likely causing over heating....but ....at your mileage,if you do not know if the timing belt has been changed.....CHANGE IT NOW!
Water pump is optional at this mileage.

Testimonial: "thank you for the very clear, step by step instructions for diagnose and remedy"
Sounds to me like the Throttle Position Sensor. Thats usually what makes the throttle "rev" But that is not going to make the oil pressure drop. Pull the codes from your car and look them up online. sometimes there is an extra fuse u can add to your panel and turn the key on and it will flash your codes via the check engine light. i.e. if the light flashes 2 times then small pause then 1 time and long pause that is code 21. if there isnt a extra fuse you can usually jump it with a paperclip and pull the codes. not really sure how to do that with yours. but im positive Google knows ;)
