Check the inside of your distributer cap, moisture will cause major problems. Start your jimmy and run water over and around your distributer, after awhile turn it off remove the cap and feel the inside for moisture...it might not be sealing right.

Buick rendezvous misfire issue


Since you changed parts, you have covered some possibilities. On the spark side, the Crankshaft sensor and( if equipped) the camshaft sensors give the information for the firing Pulse.

A wet connection on either part can certainly cause a misfire. There is also the possibility of a fuel injector misfiring due to a connection or bad ground on the injector during damp weather.

Sometimes if you get lucky you can see spark jumping on the motor by operating the engine in the dark. Mist the engine with a spray bottle of water to see if you can induce a misfire, if unsuccessful with normal weather conditions.

WD 40 often cures moisture problems.

Please rate my info.

Car sputters and engene light comes on in the morning of rainy days only


check the BAP (barometric air pressure sensor), rainy days mean odd Barometric pressure, so the sensor could be faulty, a simple multimeter can show you what voltage it is putting out, and replacing it on a rainy day might show you that it is faulty as well

When it rains, car sputters and check eng. light comes on. replace 2 of coil packs and plugs but still having same issue.


Frequently high humidity or rainy weather can cause poor performance, usually because of a problem in the ignition system. Moisture and condensation may be forming iaround or in the coil packs. Also, the ignition (suppression) wires may be old and arcing from one cable to another, causing timing issues and misfire problems. That problem is aggravated by moisture and humidity. Look for old or loose plug wires loose plugs, etc.Look for ways to dsplace water in these ares. Sometimes there isn't anything to be done and it will cure itself after warmup.
Hope it helps

After it rains my van doesn't want to start


it could possibly be defection ignition coil or ignition wires arching when the weather is damp outside. Remove the doghose and while the engine is running, spray the ignition wires and coils and see if you can hear or see the arching wires.
