Trans Sport :: 1992 Pontiac - Cylinder 6 Not Firing When Engine Hot
We have a 1992 Pontiac Trans Sport with the Chevy 3.1 V6 TBI engine.
Engine was running poor because of a faulty Coolant Temperature sensor (rusted-out pins). Changed the sensor and cleaned-out rust from the socket and now it runs smooth when cold with decent acceleration.
Problem is that cylinder #6 is not firing when engine is hot at operating temperature. Engine shakes lightly but performance remains good.
Distributor, rotor, spark plugs, spark plug wires and Oxygen Sensor were all changed 1 week ago with new ACDelco parts. What to check next?
Metro :: 97 Geo 4 Cylinder / High Intake Air Temp?
So, 97 Geo metro 4 cylinder... bought it last month with no lights on... but within 7 miles of purchasing it the check engine light came on. Code is for a High Intake Air Temp... went to take a look at the sensor first... but the sensor had just fallen out of it's mount and was sitting in a hotter area than it belonged... I plugged it in where it goes and the light went out... for about a week. The light came back on, the sensor's where it should be, and I have the same code. I figured it being close to the exhaust manifold may have damaged the sensor, so I replaced that... and the light stayed on. Since it was intermittent before, I assumed the code just didn't clear, so I've been driving it for a while hoping the computer will reset, but no luck.
So, assuming the sensor's fine, what would cause a constant high intake air temp (including when the car first starts)?
Geo - Metro :: Car Smoking After Rebuilt Cylinder Head Installation
Got a rebuilt head for my metro from a very reputable ebay seller/shop, and it smokes pretty badly after installation. I checked my pcv valve and it has vacuum at idle, and the hose is not plugged. Performed a compression check- 180 on all cylinders- okay for my car. Called the shop to see if maybe they forgot to install the valve seals, and they insisted that there is no way they would forget that.

Situation is I have a 92 F150 2WD donor truck. 5.8l will be going into my 80 F150 4X4. E4OD transmission is long gone, but I do have a 4R70W from a 96 Explorer. Bolting it together is no problem, but there are differences in the transmission controls. E4OD uses a coast clutch, 4R70W does not. EPC, shift solenoids and TCC are compatible. I do not want to use a 5.0l PCM or add external controllers like the Baumannator.
Question is, can I control the 4R70W with the PCM that comes with the 5.8l?
I'm thinking I can ignore the coast clutch output, maybe tie it to +12 through a resistor if that makes the PCM happy. Baumann's controller appears to work with E4OD's as well as 4R70w's doing exactly this. Baumannator TCS Electronic Transmission Wiring Details....

I recently did a coil pack swap to determine if that was the cause for a cylinder 1 misfire. Left to right on my 2009 se tiguan, I changed 1 to 2, 2 to 1, 3 to 4 and 4 to 3. I recently ran into the cylinder misfire again, this time on cylinder 4. The problem is, I do not know which coil fires which cylinder. I've looked around quite a bit and can't seem to find it.

View 3 RepliesFord - Crownvictoria :: 1992 - How To Do Oil Change Without Damaging Drain Plug
I have a 92 crown vic. And this past weekend I tried to do a oil change but the drain plug was really tight. So I took it to an oil place to see after I messed with it for over two hours. They did get it out half way, but had to put it back in. They suggested that the drain plug or the the pan is stripped, I even tried to use a cheap siphon hose that goes down through the dipstick and it wouldn't go all the way down. So is there another way I can drain my oil without messing up my oil pan and drain plug?

View 3 RepliesFord Ranger / B-Series :: 1992 - Wheel Cylinder Blowing Out?
'92 Ranger 2WD with 4 cyl and 9" brakes, right rear wheel cylinder keeps blowing out, replaced it twice. I've thought about maybe an obstruction in the left brake line creating too much pressure, or in the junction block on the rear axle. I believe only one line leads to there from the master cylinder, so what else could it be? Only other thing I can think of is that the right brake has a mechanical problem which is causing the forward shoe to move too far away from the cylinder, leaving no 'stop' so the piston just slides right out of the cylinder. But I can't figure that. Original adjuster star wheel was chewed up so I swapped in another, doubt it's that.

View 7 RepliesMetro :: 2000 - Rough Idle Along With Engine Shake
4 cyldr has very rough idle along with engine shake. Just started doing this. I replaced the cam sensor a few months ago and all has been well. But it started running so rough, almost like it jumped time. I was disconnecting sensors to see if motor idle changed and when I unplugged mass air flow sensor on air filter intake tube, nothing changed. Could this cause such a dramatic idle ?
View 2 RepliesGeo - Metro :: 1995 - Engine Suddenly Developed Vibration
I have a 95 Geo Metro, automatic, 125K miles, which has suddenly developed a vibration. The car vibrates when hitting around 43-45 mph, at all other speeds it is all very smooth and quiet. I thought it must be in the drive train, but the vibration turns out to be in the motor, as it is present when hitting the required rpm range when the car is not moving. I gently raised the engine at different points slightly to take the weight off the motor mounts, in the hopes of finding one that was defective, but the vibration was still there. I also checked the exhaust system for clearance all around, and that doesn't seem to be an issue.
