Geo - Prizm :: 1993 - Screeching Noise Before Car Has Warmed Up

My 1993 Geo Prizm (with 275,000 miles on it) makes an awful high pitched screeching noise when I first start my car in the morning. The noise goes away once I am in second or third gear and is completely gone when my car is warmed up. It used to just happen in the winter and now it also happens during the summer. I had all my belts replaced maybe 6 years ago. Is this a problem of loose belts or bad power steering pump. Looking at the pump when I'm turning the wheel it seems as though the power steering pump belt stops turning. I also have crunching noises comes from, I think, my wheels when I turn sharply. What could this noise be? Time for a new car??!!!

Geo - Prizm :: 1993 - Intermittent Push To Start / Engine Idle Speed Too High At Times

1993 Geo Prizm, manual transmission: Intermittent failure to start over a two year period, gradually becoming more frequent. The engine turns over every time the key is turned to start the engine, i.e. the starter motor/battery/battery connections work flawlessly. Once started the engine runs flawlessly without misses or shut downs. The only possible problem may be the engine idle speed that seems at times to be too high even after the engine is warmed up. Without predictability, the engine may fail to start when the key is turned.

Remember the engine still turns over normally. It just does not fire up. Two options exist for my predicament. That which is resorted to the most because of the speed of recovery: step out of the vehicle and push start the car by popping the clutch. The other alternative which I have been forced to utilize before because of the physical impossibility of push starting (i.e. if I had been able to push, I would have popped the clutch to start) at the time has been to wait for a protracted period and re-attempt to key start the car. This has been successful a couple of times.

Celica :: 1993 Toyota Power Lag After Warmed Up

I have a '93 Toyota Celica Standard transmission. Recently it's been lagging in power. Only happens after it's warmed up. I'll be driving along and it just seems to lose power. Have to stomp on the gas to get it to kick in. Also, at the same time, when stopped it idles really low. Cold, no problem. Took it to Toyota dealer to have it diagnosed. I Stated that it might be the MAF sensor. They checked it out and said it needed a major tune up (to the tune of $700!) Now, I know it needs a tune up, but the symptoms don't seem to correlate to that being the problem. I asked about the MAF sensor and they said no diagnostic codes came up. Is it possible the air filter is clogged? Can the sensor malfunction intermittently?

Explorer :: 1993 - Ignition Missing After Car Warmed Up

152000 miles. Religious oil changes at 3000 miles. New plugs before this started.Drove about 60 miles on a warm day. Ran fine. Went to start it again, it seemed to be running on only 5 of 6 cylinders. Carefully limped it home. It did not overheat (stayed at normal temp) and the engine never died. The next day I pulled each spark plug and had a look. They all looked fine, none looked fouled. The dead cylinder was not obvious. Started it up, it ran great. This was an even hotter day, drove off to do errands. Probably drove 5 miles. Stopped, and when I started it up again, the miss was back! Went home, and while it was still running crummy, tried running it with one plug disconnected from the coilpack at a time, until I found the one that it didn't seem to matter if it was connected or not... cylinder #2. Later pulled that plug again, fine. Plug wire measure about 5K ohms on my meter, as its the shortest one. Sounds about right to me.

Today (its about 75 degrees) I bought a new coil pack and put it in. Ran beautifully. Warmed the car up, still ran nice. drove a few miles down to the freeway, ran great, got off at next exit. Proceed to run just perfect until I was slowing down for a light, then the miss came back.

Beyond checking the compression, what else might I try? I don't tolerate mechanics BTW, I do everything myself.

Ford Aerostar :: 1993 - Runs Great Except When Warmed Up

My Aerostar is a 93 extended EB with 4.0, AT, 212k mostly reliable miles, and blue and gold paint that has held up remarkably well. When started it runs great; smooth idle, easy revs, normal as can be. But when that third pip on the digital temp gauge hits Normal the van becomes possessed. The idle will randomly drop or surge or return to normal, the check engine light will come on for a few seconds then go off, all without pattern, just kinda crazy. Today I held it at 2k rpm, then it bogged down to like 800 rpm and lit the CEL, then it returned to 2k rpm and the light cleared, swung up to 2.5k, all while I hold the throttle steady. The light does not always come on when it bogs. I see no black smoke from the exhaust and it smells normal, but it was kinda windy today.

The check engine light is not lit otherwise so I assume no hard codes are stored. I think I found the code retrieval process for the OBDI but I have not done that yet. After reading a bit in this forum I thought to clean the MAP sensor, but I do not have security torx bits to remove it yet. As background a few years ago it had an oil leak from the top rear which I ignored, and it slowly rotted a harness back there till one day the harness died leaving me running on 3 cylinders. My local Speedy Lube guy was ex Ford dealership and knew Aerostars, he did the diagnosis and repair and said it was a common problem. But he has moved on. I was also told I have a torn boot on a plug wire, but there's no way to get my ham-like paws back in there, from front or back, to verify or replace. I mention all this as background, I doubt a bad plug wire is the issue here.

It seems like an odd problem to me because the only pattern is related to operating temp. It is not a constant problem, not an intermittent glitch, but it very definitely goes nuts right when it achieves normal temp. Aside from pulling the codes, which I will figure out tomorrow, any other tests I can run to diagnosis? Any way I can trick this thing into thinking it is cold all the time?

Ford - Bronco :: 1993 - Idle Starts To Fluctuate After 5 To 10 Minutes When Warmed Up

Have a 93 Bronco, 5.0. replaced battery, IAV and had a complete tune-up. Now starts great, runs fine until it gets warm, than in about 5 - 10 minutes the idle starts to fluctuate. A little at first but eventually between 1000 to 300 rpm and will stall if you don't give it some gas. Turn it off, restart, starts fine and runs OK again for a while.

Toyota - Corolla :: 1993 - Rough Idle And Loping When Engine Warmed Up?

I have a 1993 Geo Prizm (Toyota Corolla) that idles roughly and lopes only when the engine is fully warmed up to operating temp. I changed the plugs, and wires are only 1 year old and seem to be in good shape. I suspected a vacuum leak, but have not been able to find one.

Prizm - Chevrolet :: 1998 - ABS Light Comes On When Start The Car And Then Turns Off In Few Seconds

The ABS light on my Chevy Prizm 98 comes on when I start the car and then turns off in a few seconds. The last few days the light does not go off the entire time the car is running. The light does not flash it just stays on. It's never done this before. Does this mean I have an issue with my brakes? I replaced the front brakes last year but I'm fearing/dreading rear brake replacement. I have no signs that they need to be replaced but am wondering if the ABS light is telling me I'm reaching the rear brake replacement day.

Ford - Mustang :: 1971 - Cold Engine Start Fine But Will Not Start When Warmed Up / Sluggish Crank

A cold engine crank will turnover and start normally. But stop to run and errand or grab lunch...and the warm 302 2 barrel engine will turn over very sluggishly, lke the battery is dying. If you wait until the engine is cool, an easy start is assured but that takes hours! A local repair shop has rebuilt the carb, the battery & cables are new, and the starter works fine when engine is cold. My local repair shop is out of suggestions. It seems to work a little to hold the gas pedal down on the floor for a warm engine start....but engine still turns over sluggishly when trying to start when warm. Now If I drive it.....I just drive it around town a bit then back home ...unless I stay several hours somewhere while the engine cools....but that's not fun. It is a convertible, fun to drive...and this problem needs to be solved.

Mercury - Grandmarquis :: Will Not Start After It Gets Warmed Up

Have a 2000 grand marquis that will not start after it gets warmed up. Recently had two occasions where after driving for about half hour and it's shut off, it will not start. Cranks good, but will not start. After it "cools down" it will start. Have had it to my mechanic and the dealership. They can't find anything??? They say it has to get worse before they can make it better. They don't want to start throwing parts like fuel pumps at it.

Mitsubishi - Mirage :: 1991 Won't Start After Being Warmed Up

This car has the 1.5 liter 12 valve motor and a five speed transmission. Ran pretty good until a few days ago when it died. the next day it started up and ran ok for about a half a block and then I had to pump the gas to keep it running. I had bought gas at a dinky budget station that I had never been to before so I suspected bad gas and I put in a new fuel filter which did not work. I then put some Seafoam additive in. After I got it started I revved it up a bit to try and clear things out and then let it idle for an hour or so.

The engine smoothed right out and didn't idle rough but did not start after I turned it off. I pulled a plug wire, put in a bolt and tested for spark against the valve cover. Not even a weak spark, nothing. I looked for the coil but there is no coil and I am told that the coil is in the distributor. I also saw a reference online about the crankshaft sensor possibly being the culprit. What a crankshaft sensor looks like and the engine compartment is so crowded with hoses, wires and all kinds of things it is real hard to see anything from above.

I am wondering if the coil is bad do you have to get a whole distributor ( I was quoted a price of $269 for a new one) or can you take it out of the distributor and replace just the coil.I have a brand new 154 piece Craftsman tool kit, but I am 62 years old and back when I learned how to work on cars it was a lot simpler. Now when I open a hood about half the stuff there is unfamiliar to me. My other vehicle (Chevy C20 van) is not running that great and gets awful gas mileage. The battery is new and I have never ran out of gas with this car, so they are not suspect.

Prius V :: Engine Knock If Not Warmed Up Upon Previous ICE Start

I know this issue has been posted and discussed multiple times on early Gen 3 Prius'. That said, I don't see much on it regarding the Prius v ( lowercase v for the Prius v wagon, not an uppercase ). There is also of course a TSB for earlier Prius' that had the issue.

I can readily replicate the issue in that almost every time I 'think' it may happen the next time I start the vehicle, it does in fact do so.

If I move the vehicle from the garage to the driveway or around in the driveway to clear snow, the ICE fires for a few seconds then I shut it off as the car is where I need it. Upon the next ICE start, there is a horrible knocking under the hood somewhere. Different from the previous messages and the TSB itself is that I never get an error code or MIL.

I'm to the point where if I move the car, I let it warm up completely. I figure I'm better off wasting fuel than subjecting my Prius to whatever horrible thing is happening under the hood if I don't.

Mazda - Mpv :: 1998 - Hard To Start When Engine Warmed Up

Been having this problem since this past Easter when our mechanic installed new valve cover gaskets.

When the van is hot (normal operating temperature) and you turn it off just for a minute, like to get gas, and try and restart it acts like it’s not getting enough gas. It will cough and sputter and balk. It will finally start though and after 30 second all will calm down and it will run fine.

One big problem is, is that is intermittent – meaning it won’t mess up for the mechanic and putting it on the computer shows nothing wrong.

One mechanic said it was a cracked distributor. Replaced that for $400. and same problem. I’ve also cleaned the Mas Air Flow sensor and changed the fuel filter.

Dodge - Dynasty :: 1992 Won't Start Once Engine Gets Warmed Up

'92 Dynasty is a good runner, but, once the engine gets warmed up, I shut off the engine at my own risk. If the car sits for a while with the hood open, it will start again, but attempting to start immediately after shutting off will result in the engine spinning over but no sounds of attempted ignition. It seems that once the coil is cooled down to slightly more than body temp the engine will start like nothing was wrong.
