Lack of info, but These cars are known for bad computers. The wires on the back of the harness that plugs into the computer gets loose. I would let car idle and wiggle wires at the same time. I had 2 corsicas that did this. They were 3.1L engines. My 4 cylinder corsica had knock sensor issues. What size motor do you have??? A knock sensor does the same as what you are describing as well. Give me more info and we can go from there.

    Since it is a 4, I would say it sounds like a coil going bad. . You will find the coil packs by following the spark plug wires back to the coil. I replaced a couple of them in corsicas [ great cars ] When I changed the coil on one car, it wouldn't run properly, but it turned out to be the knock sensor. I would say it may need a good tune up anyway, going by the low milage. Spark plugs , wires, air filter etc., but find the problem first. , also inspect the wiring on the coil that is on the car now, they sometimes get bad. just throwing things at you right now, but I would say start with the coil, and also check wiring going to the computer. The computer is on the passengers side under the dash. on the side. wiggle the plug while the car is running, and see if there is an up or down idle, rough idle etc. Just to rule it out. Let me know how you make out. Cheers from Nova Scotia!

SOURCE: 2002 Civic EX wont accelerate

It sounds like a problem with the transmission. The creaking could be a bad power steering pump or simply a dry/leaking rack & pinion.

SOURCE: Vehicle "Choking" While Driving

On my 2002 windstar, I had intermittent problems with the engine light flashing while the motor was accelerating or going up a hill, about 3 minutes into a drive following being left alone all night. During this time, the car engine shook and acceleration was poor. Later, the problem was minimal.

Root cause:
The coil block has one coil for two cylinders. In my case, the middle coil fires cylinders 2 & 6. When I cleared the codes and got the problem to occur again, the codes came back at the same time. I removed the cowling to access the col block. When I examined the bottom of the coil, I discovered that a crack had occurred across the resin just under the location of the middle coil.

Autozone has a diagram of the pinouts of this coil block you can download to see if your dual-intermittent cylinder misfire problem corresponds to another coil in the block.


When moisture gets into the coil, it causes the problem. When moisture is driven out of the crack by engine heat, the problem subsides.

Procedure I used for repair:

Access: Remove Cowling:
1. Remove Wipers
2. Loosen Plastic Cowling cover
3. Remove washer fluid hoses from nozzel
4. Remove plastic cowling
5. Disconnect wiper power from connection on drivers side wiper motor.
6. Disconnect wiper fluid hose from connection above passenger front wheel.
7. Remove metal cowling.
8. Change out the coil with three screws - very easy to do.
9. Replace components in reverse order.

Note: While I was at it, I changed the wires and the spark plugs. The spark plubs in the back were accessable but hard to get to without a swivel head socket wrench.

SOURCE: My 1978 Chevy truck will choke down and die

Not sure what "choke down" means. If you mean run really rich and smoke black, like the choke is stuck, look at the choke linkage. If you mean lay down and give no power, but not smoke black and not sound farty and blubbery, that is likely not a choke problem.

Look at the fuel filter. They can be mostly clogged but pass enough fuel to get by under most situations; also their internal gunk load can shift, causing a filter that was serving okay to be clogged at a moment's notice.

Check the gas cap and the tank vent / evaporative emissions system - if air can't get in to replace the fuel you removed from the tank, pretty soon your fuel pump is trying to **** fuel out of a tank that is already under a vacuum.

If those two are OK, throw an ignition coil in it. They are cheap and easy enough, and a failing one will intermittently lay down and give weak sparks. If you can catch the truck in its failure mode, try loosening one of the plug wires (either end) and holding it a half inch away from its previous mount. You should get fat bright blue sparks jumping the gap, snapping as they fly; if they won't jump that far, or sound or look wimpy, your coil is suspect.

If you change your coil and the problem goes away, give the truck a tune-up - cap, rotor, plugs, and wires, and also change the ignition module (an extra $20 for a cheapie.) Coils don't die of old age; they die of overwork, like trying to push very high voltage through high-resistance spark plug wires and across worn-out plugs. The ignition module has to handle all of the power that goes through the coil, and if the coil is stressed, so is the module. They can fail without warning, stranding you until the module cools down enough (30 minutes to six hours) that it will run again.

How to diagnose my car to save time and money

MAINTAINANCE, this is an important word ! an never assume ! tune-up is another, so begin with tune-up, spark plugs, wires, cap / rotor, fuel filter, oil filter, fresh oil, transmission filter /fluid , very important, air filter must be changed also. don't go over 45-50mph until you do all of the above dude. put some drygas in your tank, red bottle, has fuel injector cleaner in it. now get to work !!!!!!!!!!!!!!!!!1

I have a 2000 blazer that bogs down at high rpms what could the problem be?

if it is driveable, but seems to cut out, and bog down at sporatic times, and speeds then odds are it's the distributor. (the electical flow is intermittent when it should be constant) if it only happens at higher rpm then it could be the cam position or crank position sensor

Have a 90 corsica...fuel pump is fine...****** is fine but wont go over 35 mph...acts like its not getting enough fuel...please help

1st, try to ask a mechanic to check if the timing of your engine is correct. the timing might be a little "delayed" so the engine cannot work properly on high speeds.

is your engine still uses carburetor? if yes, replace the primary and secondary jetting of your carburetor. normally, the standard primary/secondary jets for a 1.6cc engine is 105/135.

if your engine already works on direct fuel injector, replace injectors with bigger size. go up 1 size at a time.

i believe the culprit here is the timing in your engine.

I have a Chevy Equinox LT with 235 60 17 tires on it.. I came across a set of 235 65 17 tires.. Can I put these on or would they affect the car/performance?

They would be fine, they will be a little bit taller then your factory tires, but you should have plenty of clearance on that model. May effect your speedometer, so pay attention to speed after changing to different tire size. Should only be a half inch difference I think, so your only talking a couple miles an hour. Easy test put cruise on 60 mph. drive 1 mile timing it should take exactly 60 seconds to reach the end of the mile.

1990 Nissan Maxima V6 a/t: vibration above 60 mph

Start off with a tire rotation. That should solve the problem. If problem presist the next best thing to do is have your wheel bearings checked. In order to check your wheel bearings you need to lift the car from the front (suspending the the front wheels. With both hands grab the tire on both sides and move with back and forth motions. If you find much play then you need to change your bearings. These things will cause movement at high rates of speed

Hyundai 1990

we will start with basics, timing
if that no good check it is firing on all cylinders
if that didnt work check compression (100 -160psi but never vary more than 30psi between all)
if that all good check fuel pressure
if that all good i would have to ecu is on its way out, one day soon youll go to start it and it wont go, just a vroom on turnover then nothing.
