PostSubject: Starting problems   Fri Feb 04, 2011 5:48 pm

I have the car all put back together and am driving it. The check engine light came on and the car was running rough in drive when stopped between 500 and 800 rpm so i took it to my mechanic(I figured it was a coil pack or ignition module, since my monte did the same thing and that was the cause). My mechanic hooked up the scanner and it was a random misfire(coilpack or ignition module). So I took the coil pack off and cleaned everything up, there was alot of dirt and everything.. I put everything back on. The check engine light is off now and it runs fine.

The only problem I have is that when I go to start the car I have to press the gas otherwise it will not start(i figured that it was the coil pack, but I guess not). Most cars should start without pressing the gas unless of course it is carbureted. Am I correct?

If your misfire was caused by a lack of spark, your plugs could be gas fouled. Pressing the gas would put the car in clear flood mode,cutting off fuel during crank.

check engine light came back on today. I am going to get a new ignition module to see if that fixes it.

DId you actually check the coils resistance? I forget what the spec is, but a coil that's out of spec is a candidate for replacement (hopefully before not after it kills the ignition module).

It might not be related but,I had the same problem. rough idle in "D" calmed down in "P" I swaped out my TPS for a used Unit I found at a JY,cleaned out the throttle body,cleaned the PCV,cleand the EGR valve,swaped out a few vac lines. problem gone.I think its a combo of the TPS solenoid and a dirty TB. JUST MY 2 CENTS!!!!! GO JETS!!!!!!!

Hey all, hopefully this is a good thread to post my question...

My Riv is having issues running on rainy days. Maybe it's sad? I'll be going to work in the morning and then it starts to run rough and then quits. I'm now in my lane, usually right before or after a traffic light and the car will just not fire up.  

After sitting there in the rain, blocking traffic with my 4-ways on while expressing my frustration in four letter expletives, and roasting my electrical system, the car will slowly come back to life and leave me feeling skeptical and late for work. Any ideas?

Is the yellow service light on, and if so did you pull codes? There is one set of answers if you do have a light (post the codes), and a different set if you don't (involving engine controls that don't set the CEL)

Are all the splash guards in place and do you have any wires dangling under the car?

Thanks for the reply, Albert. No engine light or dangling wires. There is a rust hole in the passenger rear wheel well. A coworker leads me to believe that water must be getting up there and shorting out a worn out exposed wire. The other day I drove on the interstate from Rochester to Buffalo during heavy rain with no problems. It was actually awesome.  I was told that since the car was at high rpm the current could handle moisture compared to that of sitting at a stop light.

I have plans to completely redo the underbody before next spring. We'll see.

consider removing the ignition module and cleaning it up, also get oil/dirt off the plug wires.

Thanks for asking, Albert. I haven't gotten into it because I plan to go deeper into things and take my time in a heated garage. Hopefully that's soon because I want to start in on a few things as a long-term winter project. That also means getting the underbody completely redone with new exhaust sometime early next year if budgeting works out.

What are you considering for the exhaust?
