I have a newly rebuilt engine on my 1965 Austin Healey 3000. When the engine is cold it makes a popping/backfire noise. After the engine has warmed up for 10-15 minutes, it doesn't make the noise anymore. See this video [URL] .....
View 7 RepliesI drove my friend's austin healey (forget model year, it has twin carburetors, 4 cylinder motor). The gears had a lot of torgue - all the way up to the top gear. It had a overdrive stretch perhaps telescoping the top gear to two more higher order gears. Question: Is that normal for sports cars to have such high order torque gearing. I thought sports cars gears stretched from a high order lowest gear to very low torque higher gears.
View 19 RepliesI think his problem in today's show is the fuel tank.. It needs to be cleaned. When I was in college, I drove a 1954 Austin Healey 100-4. I was young like the fellow calling in today. The car would unexpectedly stop for no reason but it would slow down the same way as the MGTD just before it would stop. I would let the car sit for 10 minutes and it would restart without issue..drive for an hour..drive for several days till it would happen again... Rust inside the fuel tank is the deal..the pick up is getting clogged.
View 1 RepliesGetting backfire or popping noise after deceleration with our cars. It didn't do it before with oem exhaust, just wondering if we're going to get a little bit from my new joe z exhaust, or do I have a leak somewhere with my installation. Or do I just need it break in a little more. How do I check for leaks , Do I just need to ramp the car and check all the flanges for where the exhausts bolts up and check for alignment issues.
View 14 RepliesI have A 2001 Santa Fe. The check engine light came on about 3 weeks ago and the car was still running fine up until the last few days it felt a little sluggish. Today I got a little muffled backfire noise. It was like a putting noise if I pushed on the gas to hard to speed up. The car has 95,000 miles on it.The car starts up with no problems and doesn't stall. Its A 6 cylinder All wheel drive vehicle.
View 10 RepliesThe other day I was leaving work and I switched on the ac. I heard an audible popping noise and the air immediately stopped being cold. I pulled over and popped the hood, it smelled like freon and I'm sure it was mixed with compressor oil as there is oil stains all around the compressor now. Did I blow my compressor? Is there a blow off valve that could have been tripped? The compressor is not kicking on now, I don't know if it is blown or this is due to all the freon spraying out? It had been squealing on startup for a little while, I assumed it was a belt.... 2002 echo....
View 4 RepliesSince new, I've noticed that my truck makes a ticking/pinging/tiny backfires when cold. I can't really hear it unless I open my window(s) as it comes out the back end and isn't anything in the front end (...its an exhaust issue). Is the truck just running rich when cold?
View 6 RepliesI have been having this odd issue where my car will back fire after a cold start. It only happens when getting out of first gear and going into second while driving (it happens as soon as I press the clutch pedal all the way in, and stops as soon as the clutch pedal is back out). It doesn't happen all the time, just every now and then. My only explanation of this would be that I live a mile above sea level (I looked at the FAQs and know that the car will act like its about to die on a cold start, yet it doesn't). So with my only "explanation" of this phenomenon being that I live a mile above sea level and the engine running rich for a few minutes after start up. My car is stock with the exception of the flapper mod.

Just finished an 11 hour highway drive and I am getting a popping noise - like a lot of popcorn popping at once, or water boiling. It sounds like it is coming from the engine and only happens when the car is in gear and the brake is on. It does not happen when the car is moving.
I have noticed this noise before, it occurred a week ago after about 500 miles of straight driving when I stopped for gas. About 100 miles later my alternator died. Since then the alternator has been replaced and the car has been running fine on short trips. No sign of any trouble.
Temperature gauge on car does not show any overheating and there is no coolant leak. Turned off AC with no effect on noise.
My car has 200,000 miles, replaced the engine at 163,000.
2005 Ford Taurus 3.0 engine. Only at idle has a popping noise out of throttle body. Found lots of people with same problem but no fixes.
I did find out noise goes away when unhook alternator wire and comes back when reattach. Found someone replaced there alternator and that didn't fix it either. I think its electrical?
I've had this tapping in my engine for a few weeks now and I put it in drive then heard a huge bang from the front of my engine and then started making a very loud popping noise that almost sounded like air leaving the valve cover...

View 1 RepliesI have 65" Pontiac Catalina, sometimes the ignition does not stop spinning the starter motor, I think it is because the switch is not springing back to run position. If i turn the key back to off it stops but engine stop running too. I am afraid of burning up the starter motor, what do you think could be wrong.also is it just replace the tumbler or the whole ignition housing as well.....
View 3 Replies2001 GL 1.5 Litre. Car occasionally hesitates a little with AC off, but runs pretty well. But with the air conditioner on?
Stalls about 50% of time when backing with A/C on. From stoplights, sputters all the way through intersections with A/C on, sometimes backfires. On a few occasions, the Check Engine light will blink on and off while it's doing this. After it gains a little speed/rpm, though, it's all good again, light goes back off.
Had full tune-up just before we bought it 4,000 miles ago. Air filter clean. Not sensors, because the CEL goes back off by itself. What the heck? How could the A/C cause a backfire?
I have a problem with my 01 santa fe. When I start it the engine runs rough and when u try to give it gas it pops or backfire through throttle body and air intake tube? Checked the timing belt its ok hasnt slipped.so im stuck at this point.
View 8 RepliesOver the past few months my '13 350 occasionally seems to hesitate when starting from a light, in a parking spot, in general no/low speed maneuvers. It doesn't do it every time, and it's not a hesitation with engine bucking, backfire, or noise. It just feels like the power takes a few seconds to come on when I hit the pedal. Sometimes. It has been interesting a few times on highway on-ramps...
At first I thought it was my accelerator technique, using the wrong foot angle, but I've been careful to apply the pedal correctly. Since it doesn't feel like the classic engine miss I was wondering if there are any other things to consider, such as transmission (hopefully a software update or something else simple) or anything else.
Looking for a good diagram of the complete vacuum system on the AEB 1.8t 99 passat. I am throwing a 1136 code which is indicated as a "Manufacturer controlled fuel and air metering". I recently finished a complete rebuild and engine is finally back in but running in limp mode. During the rebuild, I used mobil 1 synthetic as an assembly lube for all internal components including valve train.
I immediately wet fouled O2 sensors and spark plugs. After repeated removal and cleaning for plugs and O2 sensors i have progressed beyond seeing the "wet" fouling but plugs are still very rich, black in color but dry. Engine starts and runs at idle(lumpy) consistently and will run for as much as 5 minutes but very rich. If i rev engine to 3000-3500 rpm it will "POP" or backfire and immediately stall.
I would like to add power steering to the truck. What I need to do and what parts are required. Could a 65F100 come from the factory with power steering?
View 2 Replies1991, F-250, automatic, 150,000 miles, two tanks. Used mostly for towing an RV plus some pleasure. Not in daily use. A month ago I parked it and a few days later cranked it up and found it wouldn't run over thirty MPH. There was some high pitched backfire in the engine compartment and the trans. wouldn't shift. I parked it and the next day it wouldn't start. When I turned the key on the fuel pumps (either tank) ran continuously. Towed to a garage (I am not a Mechanic). They have replaced the fuel pressure control, checked all pressures and it still won't run right. The problem is intermittent. My tranny man said the trans was good. My mechanics don't know what to do. I bought it in 1998.
View 3 RepliesI have a 1965 Chevrolet with the original 396 engine. When I purchased the car, I noticed the fuel pump was wet with fuel at the weep holes. I replaced the pump with a new one. This pump also leaked at the weep holes. I thought dirt may have been in the fuel tank and the check valves were stuck causing the leak. I installed a glass inline fuel filter before the fuel pump and installed another new pump. There is no dirt in the filter. This pump also is leaking from the weep holes. The pump only leaks when I give it full throttle and bring the car up well over 65 mph. I would like to retain the stock type of fuel pump. I'm wondering if the pump push rod is a replacement at some time and too long.

I am attaching a link to my thread in the 1960's truck forum : [URL] .....
With my limited skill level, I have given up! It could very likely be something I am doing wrong with the diagnoses/troubleshooting.
Basically, When I turn the key to start the truck, I get a clicking solenoid at best and what appears to be a total loss of power. Not even the dome light will come on. The starter is new as is the solenoid.
