Hi I really hope to get some tips here. A bit of background info, I am disabled and use air assisted gas/brake hand controls. These actually have a side benefit in that I can feel the acceleration and idle.

While driving my van on a 40 mile trip (ac was on, 95+ weather, 65mph on interstate) I felt the engine idle rough, I gave it more gas and felt no response, and then it stalled. I did not see if the check engine light had gone on. A very similar stall happened 8 years before and the apparent cause a terribly clogged air filter. Since that time the van has run great until the 40 mile trip. After the stall I was towed to a shop where the van restarted but I had the air filter changed just to be sure. Of course the shop did not believe or agree with my suspicion or solution. Thirty minutes later I was back on the road completing my trip, running errands and then the 45 mile trip back home, with no further problem. The next day was a 55 mile drive with the rough idle, no gas response and stalling about 350 feet from my destination. After sitting for five minutes it restarted made the 350 feet and stalled again. Took it into a different shop, but no code showed, nothing in the history, they drove it 17 miles lots of tests (don’t have specific tests) and now I’m waiting for it to happen again.

Any help is very much Appreciated


Does anyone know about how much these tests would cost??

Idle Air Control Valve (IAC)
engine crank sensor
EGR system -electric EGR transducer (EET)
ERG valve
O2 sensor
throttle position sensor
AIS (automatic idle speed motor)

fuel filter/pump-this was done
