98 Buick Lesabre.3.8 Driving up hill, down hill, coasting, it doesn't matter. 1 or 2 times a week the engine just dies. Sometimes I can catch it full throttle and it will pick up and run fine. or throw it in N on the fly and restart instantly.
New fuel pump and filter
Usually starts good. some times I have to stop cranking it after 5 sec 1,2,3 times before it starts. This only happens 1 time every week or two.
I've been told after the engine is running you can un plug the crank sensor and it will still run. So this rules that out, Yes? Also told Cam sensors are not usually intermitent they either work or don't, Yes?
It's been doing this for 1 Yr

My Durango starts to jerk when I slow down then try to pick up speed again. At one time it wouldnt let me go faster than 25mph and the RPM would shoot from 1 to 3. What could be wrong?

When i turn on my heater in my Ranger it boggs down my engine any one know the problem? and the RPM getting on the highway it takes more and more everytime i thank i need to change the Fluid and Filter anyone have any (!) (!) Thanks

I have a Jeep Grand Cherokee 5.2L AWD 1997 Model. Used it for a while before shipping to West Africa where I am on assignment. I used it for two years in Accra - Ghana without any probles. Drove it to Abuja Nigeria for my next assignment and after a coupl of months, vehicle started building up presure in the engine. I lost the first radiator and shipped another one from the US to replace it. That one bursted within two weeks. My local mechanic felt it was the thermostat. He took it off and I replaced the secone radiator. That one has again bursted busted again as the presure has continued. Once I drive it for a bout 30 to 45 minutes, the radiator hose becomes very hard and the radiator stars leaking. Now, the point where the top hose meets the engine block (top cylinder is now leaking. Can someone tell me what is wrong with the vehicle?

I recently overhauled my son's 1993 Jeep Wrangler, 4.0L. After reassembling, the engine will start and as long as I keep it at 1000 RPM, it will run, but as soon as I release the gas pedal, it will sputter and pop at idle and then die. I have replace the ignition coil, pickup coil. Any ideas???

i have a 93 chevy 1500 z71 with a 350 motor. I have owned the truck for several years and everything has worked fine until recently. the four-wheel drive wont lock in anymore. When i try to engage the 4x4 the fuse blows under the dash. I have replaced the fuse and the same thing happens each time. anyone know what could be wrong?

I have a 1998 Isuzu Hombre (S10) 2.2L that is "stumbling" during mild acceleration and when trying to maintain a steady speed. Idle and hard acceleration are fine, cranks with no problem. I'm thinking EGR or vacuum leak or both, anyone else have this problem or know the fix for it? Thanks in advance.

My S-10 has recently developed a miss that seems to occur only when the truck is under some stress from a climb up a long hill. Truck runs great on level ground with no indication of a miss, but when the rpms drop below 2500 or so as going up the hill a miss seems to develop that is accompanied by a subtle puh, puh, puh sound from the engine. Downshifting helps, but I am having to downshift to 3rd about 2/3 of the way up a hill that I used to be able to pull in 5th gear until 9/10 the way up the hill. I have replaced plugs, wires, fuel filter and ran a container of fuel injector cleaner through the gas tank. These seem to have helped overall performance, but not the hill pulling issue. Any thoughts about this problem ?

My 96 grand cherokee v8 has broken vacuum lines under the hood and the heat/ac controls only work on defrost no matter which setting they are on. I looked all over and cant find where the vacuum line runs through the fire wall. I also had glovebox and heater controls out but it was still to tight to see where line runs out. Can anyone tell me what color the main line is and I will just run a new line and tap in behind heater controls if I have to. I looked at 2 diff. grands a yr or 2 older. 1 had the 4.0 and a line ran in next to a/c plumbing but mine doesnt.It doesnt seem to have broken off flush there either.The other had the v8 but lines and tees were a whole diff set up.Any help would be greatly appreciated.
