Chevy :: 1989 G20 Shuts Off When Coming To Stop Or In Idle
Jun 6, 2011
Like the title says, 89 Chevy G20 V8 5.7l. When coming to a stop or in idle while in drive the van will shut off. Here are the symptoms.1. When driving below 10MPH the oil pressure gauge will drop to 0 and then the van shuts off.2. When starting the van a nice white plume of smoke comes out of the exhaust.3. Van had been chugging a bit when stopped and the AC was on. I replaced the fuel pressure regulator today thinking that possibly the engine was getting flooded when slowing down, but that did not fix the problem.

I posted a few weeks ago about a problem I fixed with the MAF ( leak after the MAF ). 89 GT 111k miles, ( car restored to showroom condition ) Last week I pull to a stop light and idle is at 2000 RPM. Shut engine off and restarted and all was well, and idle back to about 800. I know something was wrong before hand as the car was pulling without my foot of the throttle. This happened again when I pulled into my driveway so let it run like this and when I pulled the plug on the IAC and idle dropped to about 600.
I took the IAC off the TB and cleaned it which did not look too bad. Installed IAC but left it disconnected and set up the idle on the TB according to the shop manual to 750 RPM. Shut engine off connected the IAC and followed the instructions in the manual to reset the ECU by disconnecting the battery for a few minutes, letting it idle for 2 minutes shut engine off then restart.
Well it was good for 2 days then started the same thing, 2000 rpm at idle..for the time being I have the IAC disconnected and set the idle up on the TB to about 850 RPM.
I have been driving the car like this for 4 days now and no running problems what so ever. Funny thing is no check engine light and no stored codes during this entire episode..Had my friend with an earlier OBD scan for codes and clean.
I hate shot gunning parts by replacing the IAC. Does it hurt running the car with the IAC disconnected or should I foot the bill and get a new one ? and hope that is the problem..or could something else be causing this ?
I checked for any vacuum leaks using my propane torch no change in idle. IAC problem on 89 Mustang GT 5.0 manual trans.?

My 1992 Buick Century frequently shuts down when coming to a stop or slowing down to make a sharp corner. I'm always able to restart it. I thought it was a torque converter lockup problem, but my transmission specialist said the transmission is okay. Last month, after the car died completely, I had the crankshaft sensor and harmonic balancer replaced by Firestone. Could it be the same parts that malfunctioned? Or, could it be another issue?

I have a 89 chevy 1500, 5.7 pick up. I beleive it's referred to as the c/k series.
Recently I've been having some issues with stalling. When the engine is cold everything runs fine but after warm up I've noticed the problem start occurring.
When I'm doing a slow turn ( any direction) , backing up, or in stop and go traffic, the truck want to stall when I touch the gas pedal. Once I get past the intial slight throttle it picks up and does fine.
I've replaced the distributor cap and rotor, plugs and wires, fuel filter and even the fuel pump( mainly because it never gauged fuel correctly but I thought it might have a pressure issue).
Nothing seems to work and I'm not getting any codes.

Last night transmission in my beloved '89 Caprice Wagon let go, it slips completely in all the forward gears. I was coming down a long hill using low gear for several minutes and when I put it back into OD at the bottom it seemed to skip a little but it was still making power well enough. I got off the freeway at my exit and stopped at a red light, when the light changed I was revving high but barely creeping through the intersection. I pulled over and this is what I figured out:-All the forward gears make essentially no power any more.-Reverse seems to work normally.-The fluid is at a normal level and not discolored or burnt smelling.
I don't know if this is related or just an amazing coincidence but the water pump also seems to have blown the gasket at the same time. I must have just happened within a few minutes of me pulling over because there was still a ton of coolant left and the temp was still in the normal range. I don't see how they're related but, like I said, the timing is too coincidental. Earlier this week but just a few miles ago I also topped the power steering fluid and oil.
It's a 200-R4 transmission, is it toast? Why does reverse work but all the forward gears slip completely? Is the water pump just a red herring? I did drive the rest of the way home in reverse.

A few minutes into a summer's evening drive, the engine shuts off and will not start. We've determined that there is fuel to the fuel injectors and they are clicking. There is a strong spark coming from the distributor. When there is fire, from cranking the motor, it results in a backfire in the intake manifold. As for the OBD, it's a 16 pin connector that when I shorted pins 5 and 6 (top-right pins) with a paper clip, gave all code 12s (not sure if it's OBDI or II)....

Well i have a 1992 for explorer 4.0 all lights seem to dim kinda surging at idle or coming to a stop. Has new battery, battery cables nice and tight new alternator. My Volt gauge on my cluster jumps from 12 to 14 volts. battery light flashes seems to be getting worse. Was having similar issue about 1 year ago found a injector giving up. Replaced injector and worked good for a while. Wondering is it common to have that issue with injectors causing these issues. Doesn't seem likes its missing firing.

I have had my golf R for 7 months now and ever sense I got tuned I have had this little issue. Besides this the car is amazing but ever now and then the car while coming to a stop and put it in natural to come to a stop the idle will go to 500 then come back up to 1200 then rest at 800. I'm getting my PCV replaced tomorrow. I'm um stage 2 tune fully loaded with Bsh intake full 3" exhaust.

2009 Ford Explorer - 6cyl -4L - 36K miles. This morning driving it, I came to a stop sign and as I was braking, the idle starting going up (and up and up) to the point where I had to shut off the engine. When I restarted it, everything was fine and of course, I can't reproduce this. I have the shop manual and couldn't find an IAC valve on this vehicle which I'm assuming it doesn't have. I'm sure I didn't accidentally hit the gas (as opposed to the brake which I know I was pressing down on when it was happening). Years ago I had a different Ford which had the exact same symptom and replacing the IAC solve the problem.

for the past week we have been trying to figure out what is wrong with our truck. We recently bought it and it ran fine. Then got in a minor accident just a fender bender and it started acting up so I got towed to garage. First it would run when cold, but when hot fuel pressure would drop to 28 psi.
So I put new fuel pump, it started but still did the same thing hot 28 psi fuel pressure shuts off. So I put regulator on it, then had 0 fuel pressure won't even start. So got a another regulator thinking I got a bad one, still 0. Checked relay, there fine. I'm gonna check lines and see where fuel stops at but everything is new on it.

ive actually owned 4 volkswagens one of which was a 2002 big turbo gti which made 325whp..... so now i have a 2005 Jetta GLI with about 41k on it. This car has a serious idle problem. Start up is fine and it runs great and hits boost perfect. It has a 6 speed, APR chip intake, forge DV, and DP. When i come to a traffic light and come to a complete stop after about 10 seconds it hiccups and the idle drops to abou 600 and then back up to normal idle. It will also do it if i just leave the car running in neutral it will randomly stutter. I have new spark plugs and new fuel injectors and i only use 93.

I drive a 2006 Scion tC with 96000 mileage. The car has been getting a lot of problems lately.
1. P0741 torque converter engine light
2. Lost in power
3. Lost in MPG
4. Shakes a lot inside
5. Low Idle
6. engine shuts off on reverse and d mode
7. Noisy strange sounds
8. Gear slip around 2-3
9. RPM goes high at low speed.
I Replaced,Spark plugs, coil plugs, engine oil, coolant, steering fluid, brake fluid. I need to to replace the transmission fluid. I was told by a couple of shops to get a transmission rebuild....
I also read someones comment online: "It's your transmission. Your torque converter is bad. There is too much torque as a result. When your car is in neutral or park there is no torque being created. When you leave the in gear idle state, the torque is relieved. That is why the problem will go away when you hit the gas."

I have a 1999 f-150 4x4 4.6 5spd manual 180,000 miles on the clock. My question is, when coming to a stop i push the clutch in an the idle hangs at about twice what it should be until i come to a complete stop then it drops to normal. It's not like somethings sticking cause it will stay at the high idle as long as were rolling but as soon as the wheels stop turning it drops down.

I have a 2007 Chevy HHR. A couple of weeks ago I had to change the caliper on the driver's side of the car. I had some squeaking after, but bled the brakes and the squeaking went away. The other day I took the caliper off and painted it. I have custom wheels and you can see the caliper plainly, it was rusted so I painted it. Now I am getting the squeaking again, but it stops when I apply the brakes. I bled them again, but still the squeaking. This is driving me crazy. Could it be the "chirper" that is dragging on the rotor? Also I want to add, it squeaks until I get up to about 45 mph. Then it stops. And as I said, it stops when I apply the brakes.

My brother's 1995 chevy lumina 3.1 engine has been dying while braking for a stop and while reversing. Has replaced fuel filter, map sensor, throttle sensor, o2 sensors and still no change. He says he doesn't believe a tune-up is the cause either.

I have a 1989 Dodge RAM250 that has a 318 5.7L V8. It has throttle body injectors and I had to replace one of them. I did that and the engine runs grate! My problem is that when you put the vehicle into Drive or Reverse the engine quits. The only way to keep it going is to left foot brake it and rev the engine up.

I've read tons of posts about the security system and passlock on the ignition...but my truck does not have a chip key, as the dealer even looked into the key issue with me. There is no chip or resistor on this thing at all.
So, with that said, I have the identical problem as the passlock system people do. The truck will start, then stop, and the security light flashes at me. That's the last thing I want flashing me at 6am when I'm trying to leave for work.
It only happens about once every 2-3 months, but I want to eliminate the problem as I have a feeling one day it's not going to start on me and then the real problems will start...

96 chevy camaro 3.8. i got a problem with the idle temperature, just replaced the water pump and thermostat (180 degree). when driving around the cars stays at a constant 180 temp but when sitting and idling for more than 3 or 4 minutes the temp starts to climb and gets up to about 230-240 which i know is not good but that's when the fans start to kick on. The system is clean all new antifreeze, no air in the system every thing ready to go. I know its not normal for the temp to climb that high, what else could be cause this high temp at idle?
