Caprice :: 1986 - Engine High Idling Suddenly After 3 Or 4 Minute Of Start Up
Dec 6, 2013
When start my Caprice (1986) carb-- I used to step on the gas pedal (half step is more than enough) to start the car.
Once the car started it's idling normally, but suddenly after 3 or 4 minute the sound of engine go high idling as if I stepped on the gas and that is remaining for long time even if I step full gas, and if I turnoff the the engine and pull out the key, the car will remain working hardly and shaking like crazy before it completely stop.
What is the problem with my 86 Caprice Brougham? is that problem easy to fix?

I love my '86 Mustang GT convertible. Currently at 106,000 miles and running strong. The problem is searching at idle. I have replaced every sensor that me and my mechanic can think of. New plugs and wires along with rotor and distributor cap. The engine will start searching, i.e. idling up and down, and at time stall. If I apply slight pressure and idle up to 1,000 RPM the searching stops. Hard to do sometimes as this is a stick.

I just got a 1985 Caprice Classic, V8 305. I sometimes have trouble starting it when the engine is cold. When I received the car from a family member, he gave me some spray for the carburetor. This does the trick, but I would like to fix it so that I do not have to resort to this.
The visor has some instructions for starting the engine. The directions say to depress the gas pedal once before trying to start, and 2x when it is very cold outside. I'm concerned that the car won't start at all when the winter comes.. Where should I start to troubleshoot this issue?

I just got a used Hyundai Santa Fe (2004). I was so excited until about 50 miles of driving it. Here is what happened:
I was idling at about 20 mph when all of a sudden the engine jumped (a little bit) - the RPM went down to 0 and the check engine light came on. I pulled to the side of the road and put it in park - then the car went back to normal like nothing happened, it didnt stall all the way. I was concerned and took it back to the dealership and they did a diagnostic test on it and it came back negative, nothing was wrong with it.
My boyfriend was driving up north with it and it happened to him, this time, it stalled. He said that the engine jumps a bit- but all of the lights go on on the dash. I remember it smelling pretty hot when I opened the hood before with it happened the first time, so I asked him to open the hood. He said it did smell hot. He checked the coolant and it was empty. It looks like there is fluid in it from the outside, but that was just the line that previous fluids had. He put coolant in (not in the actual radiator, but in the place where coolant goes) and it still stalled. I didn't want him to drive it anymore for fear of something worse happening, so there it sits.
Is this something that happens with most cars, or this kind of car? I am kicking myself for not purchasing the extended warranty, but I didn't have the extra cash to add over 1k to the price. Could it be just the coolant needing to go into the radiator? Do Santa Fe's typically shut down before they overheat? I was doing some research and it seems that cars stall because of either the fuel system or electrical system.

I have a 92 caprice 5.7. Vehicle had suddenly stopped ... Providing fuel to the tbi. I immediately checked relays etc all were good. Then I figured it had to be the pump because I didn't hear the whirl of the pump with the key forward engine not cranking. I replaced the fuel pump. Still same problem no fuel. I found the 20 amp fuse blown that sits next to the 2 relays. I replace the fuse then the fuel pump got energized as I cranked the engine it almost started but then the fuse blew again. I have a short in the circuit I believe. I don't have a wiring diagram,what else is on the fuel pump circuit so I can have a direction to start in to find a probable bad wire.

So my car was fine when I drove to the store, with no AC on. After that, I wanted to drive to a hotel, which is 1/2 of a mile away. Before I drove there and after I started my car, I blasted my AC (turning up to #3). On my way there the car was fine. When I drove into the parking lot and braked, the car suddenly turned off by itself showing the battery light. After the car turned off by itself, the fan (not AC..
AC doesn't run when engine is turned off) was still running. I freaked out, immediately turned AC/Fan off and restarted it. It was successful after the first try. So my question is...what caused the car to turn off by itself? Is it because of my AC? I know FOR SURE...it's not because of
1. timing belt because i recently changed it.
2. battery but i installed a brand new last summer.

Has issue with Forenza idling at very high RPM after start up? I've got a Forenza Wagon with a 5-speed that occasionally will idle at 3100 rpm for 2 or three minutes or a mile or so after starting. The other morning, it was stuck at 3100 for 15 minutes and about 8 miles. Manual transmissions will be more evident since the high revs occur when the clutch is pushed in.

2004 Prius with 109,000 miles. It's been in an accident before (and you can tell, the front right fender is a bit misaligned and the doors have a paint covering abrasions).
However, the car is making a ticking noise every minutes or so. The sound is originating in the Hybrid Synergy Drive converter inverter box and about every minute for about 5 or 7 seconds or so there will be a ticking or clicking noise. This happens when the car is idling, driving, and even a minute or two after car was shut off. The mechanic next door to the dealer didn't know what it is and the dealer is giving me a 30 day. What could this clicking be?

My 1997 ford f150 4.6 triton runs hot after 1 minute of idling. I changed the two coolant sensors, flushed the radiator, and changed the thermostat. I also went to have a diagnostic done at two different places and nether one could get a reading....

My 1986 celica gts stalls only after the engine has been off for approx. 10 to 20 minutes. It starts fine, but stalls as soon as it starts, unless i keep my foot on the gas for about 5 to 10 seconds. After that it starts and runs fine at all other times. I've changed the coolant temp. sensor, but condition still exists.

I have an 86 F150 that is idling rough. It used to cut out on me until I replaced the fuel pressure regulator. I have read in other posts that the problem for my rough idle could be leaking injectors. When I replaced the regulator I found a bad injector. My question is that if I check my fuel pressure, with the new regulator, would the only way I would lose pressure be that my injectors are leaking?

I have a 2001 Santa Fe that I am getting road ready for my son, The engine has recently started idling very high, 2500 RPM at startup. I disconnected the IAC servo and it drops right down to about 900 RPM. I replaced the IAC with a brand new one and it does the same thing at startup, 2500+ RPM. Checked vacuum hoses / tubes. I replaced 2 crack / dry vacuum hoses. Same problem for a while, then idle went down to about 1250. Started to drive it, test ride. while accelerating, seems OK as soon as I take my foot off of the gas, idle goes to 2500 - 3000 RPM until I apply brakes and then it drops back down to 1000 or so. (SOUNDS LIKE A VACUUM LEAK PROBLEM. I CANT FIND IT, IVE BEEN THROUGH 2 CANS OF CARB CLEANER AND HOURS OF REPLACING ALL VACUUM HOSES.)

My Chevy Venture 2003 approx 120 thousand miles is idling high at times. It will drive fast. I can feel it speeding up even when I am not pushing on the gas. When I put the car in reverse it flys backward (I have to keep my foot on the break to back up at a safe speed) and then when I put the car in park the engine is VERY loud. Again, this does not happen all the time. Usually when I drive it over ten miles. I thought it might have something to do with the AC, but I played around with that (driving with and without the AC) and that did not factor in it.
I took it to my own personal mechanic and he couldn't find anything wrong with it. I then took it to a dealership and they said they couldn't find anything wrong with after doing their hundred dollars worth of diagnostics and said they needed it to actually be doing it..what they called a hard fail...for them to know what was going on. . They drove the car for quite some time and nothing happened. I drove it all this pass weekend and nothing happened. It might go a week or so without doing it. Thenn it does it. Usually I can turn the car off and restart it and it will be back to normal. The check engine light is NOT on. Any clue as to what might be going on?

I have a 390 FE engine and whenever I am idling or waiting at a long stop light my engine temperature goes from the regular temp of 180 to about 190 to 210. How to keep the temp normal when idling? I have checked my fluids and they all seem to be fine, I don't know why it would be doing this.

Every morning 1.8T idles high when warming up usually takes a minute or two to idle down. When your running late kind of annoying when I drive before idle goes down to normal brakes seem way to responsive and jerky...

I have a 94 Caprice L99 4.3L V-8 won't start . Car has been sitting about a year with a full tank of gas. I parked it because I was having hard start no start issues during rainy or really humid weather assumed it was the opti distributor . The car would start after prolonged cranking. Saved up for parts now I have no fuel pressures at the Schroeder valve I pulled the fuel filter it was clear no fuel there with the key on. I can feel the relay click and hear the fuel pump cycle but only after I ( bump the starter ) but no fuel pressure.

My dad has a 92 Caprice with a v8 in it. I couldn't tell the liters. It also has an automatic transmission. I went to start it to move it today and it cranked and cranked almost like it was empty on gas. It kept making the sound as if it was beginning to start and then it slows back down to just cranking and cranking. I'm thinking something fuel related.

i proudly own a 1986 4runner and i loved it ever since i got it. but i noticed on the way to a buddies house, a really high pitched squeaking noise...almost like a mouse. I just set it aside and turned up the radio. well this morning it was really getting worse. it was more audible and I am sure others can hear it in the parking lot of my school.
Also, I have another problem (trying to kill two birds with one stone here) i went to start the truck the other morning and its getting really really cold, about freezing point and when i started it up, the engine was idling at about 500rpm and there was a really loud noise under the hood, it sounded exactly like a vacuum cleaner. I quickly turned it off, hoping the started didn't stick or something, but the engine stopped and the vacuum cleaner noise stayed for about 4 or 5 seconds. I waited a few minutes and tried again and started right up and idled correctly. got to school, turned it off and started it back up and started correctly. went out there in the afternoon and it did it very shortly and just idled right. it still does it just barely every morning I start it.
