Having problems with your GMC Sonoma ?

I have a 1997 gmc sonoma, 2.2L, manual trans. When I try to start it, it usually cranks and locks up like timing is off. It backfires sometimes. Then if it starts, it misses and backfires sometimes. Then it will straighten out and run great. Other times it start great and runs great. Usually backfires when weather is wet, rainy.

Sputtering-missing-vibrating-knocking-backfire-bucking Sometimes my 2.3L runs great. Then for no apparent reason it will start vibrating and bucking, along with a huge loss of power, even backfiring. I have to mash the gas to maintain 45mph. Its almost like one of the coil packs stops working. I can smell fuel while this is happening. At idle it will still sputter and vibrate and want to die. Plugs/wires are new (thought it might have been a shorted wire) Sometimes it will buck a few times then

I have a 96 Mercury Grand Marquis. The car lurches while driving feeling like it will conk out. Usually when going uphill on the highway and trying to accelerate or maintain speed. This does not happen all the time and usually starts after drving about 30 minutes, but sometimes it happens after drving just few minutes.Then it will do it when slowing down or stopping and trying to accelerate. We just had the right catalytic converter replaced. It ran great for 1 day then started doing it again.

My '99 Dodge surges when I go out to start it. I usually have to cycle the key at least three times before I try to crank the motor before it will start at all. It does this every time, however, sometime it takes more attempts than others. It has taken me up to 5 minutes to get it started before. It always starts eventually, and when it does, it runs great. No problems with power at all. When it's surging, the pedal is completely dead. It will not move or do anything other than surge. After a fe

My 98 Jeep Cherokee Sport runs great. But sometimes, for no reason at all, when I try to start it it does nothing. No click, no noise, etc. After a few minutes of pressing the gas pedal, brake pedal, and pulling the gear shift back and forth, it usually starts up and runs fine. I don't know if that has anything to do with it or not, I just try anything. It did it again today but it didn't start back up for about 1/2 hour. I don't want to get stranded! Any ideas??

1966 Mustang. Driving in 90-100 degree heat. Starts great when engine is cold, but when it gets hot, car will die instantly (no warning, just shuts off). Usually starts right back up, but sometimes struggles. In addition, after engine is hot and car sits a few minutes, it struggles to re-start. Mechanics have said I do not have an ignition problem. I've researched ''vapor lock'' and heat-related problems concerning fuel and am leaning towards that. Fuel is visually bubbing in the glass filter. L

Usually once I cold start it, the motor would fire straight up and rev between 1500 and 2000 rpms. Now it will try to start and sometimes stall or just jump some the kick up to about 1000. Also, when the motor is warm and you restart it, it will miss for alittle bit then smooth out some. Now I posted once before on here and I was told to change the fuel filter, and I did. It ru

My 97 dodge pickup 318 engine will miss sometimes and some times it will run just fine. it will do this while driving and just idling. Pretty much the same issue but with a 95 5.9L. Usually will spit and sputter, surge then lag. It will do this a few times then run OK. This happens mostly about 5 miles after I start out. Seems to happen sooner if I let the engine warm up on a cold day. No Check Engine Light. Sometimes it will be fine for a few days. Truck has 114,000 miles.
