Friend if it backfire then you must check your oxygen sensor to see if your engine running rich , thats mean too much fuel cominng to it , more dangerous thing is if you have a leak from the intake valve . finaly your sparking plugs may not firing well in some cylinders that makes unburned fuel to comes out from the engine to be burned in the exhuse tube.

1990 jeep wrangler runs rih won't stay running replaced map sensor and temp sensor


which engine,? the have up to 3 choices.
rih?
what are the full symptoms,
did you do the full listed 60k mile tune up on car?
sparkplugs,wire, cap rotor/filters? no engine runs right with bad spark
unless it's a diesel.
starts good
runs good or bad hot or cold engine
idle at 800 RPM hot?
stalls> when hot and cold engine
lost of power
bogging
misfire,
learchs>

only stalls , but runs perfect even up hills, at wide open throttle.
fresh gas, or 1 year old?fuel.
can your fast right foot , save the stall, and easily?

ok stalls 101.
1; lost 12vdc to EFI system.
2: lost engine compression.
3: lost spark.
4: lost fueling or floods
there is a simple test for each.
do you want more guesses, or how to do tests.
can do both, but my guessing fails 99 /100 times.

tune it up
do the right foot test. those are always first. on stalls.
always.

1978 monte carlo would not start until i blowed air back toward gas tank.. starts but wont stay cranked,,,,run rough and wont idle,,then shuts off. changed sparkplugs and wires..took off distributor and...


Sounds like vapor lock in the gas tank. I would try replacing the gas cap before doing anything else.

Sometimes the only solution is the easiest and last thing you try.

Did a tune up on my 91 dakota, but still burning lots of gas. change wires, sparkplugs, cap, rotor, and oxygensensor but still burning gas out the tail pipe


Try running fuel injector cleaner through the gas tank. A fuel injector might be stuck open, letting lots of fuel into the engine. Also try replacing your fuel pressure regulator, and inspect the fuel tank return lines.
Good luck

Tuned up car changed 02 sensor full tank of fuel still running rough


Oxygen sensor only report the condition of the engine the rough running condition can range from a worn sparkplug wires to worn sparkplugs to valve problems to injector problems. with the cadillac deville a tune up should be the first attempt to smooth the rough idle with the inspection of the cap and rotor cap and rotor do have a tendancy to arc internally and create misfire so does sparkplug wire that can leak spark voltage to ground and create misfire. the spark plug wire especially if they are brittle and hard can create issues

My 1992 jaguar won't start


Check to make sure the firing order on the wires is right. Also make sure the wire from the coil to the cap is tight and well connected at both ends. I have also forgotten to put the rotor back myself more than once..If you have both spark and gas..it has to fire. If one is missing you don;t go....

T have alot fuel coming from the exhaust, car smoking ; what to check


check your sparkplugs. maybe its time for a tune up. if you have gas coming out of the pipe your not burning the gas in the cylinder. put some freash plugs in, new wires, cap and rotor, maybe a coil if you have the cash. it will help you car run better, and you will save money on gas.

Pasenger side isnt firing with new plugs and wires


Recheck the rotor position and spark plug wiring for correct positions for starters. camshaft sensor?
-------------------
You need to bump the starter over till you get the timing mark up on the front of the harmonic balancer to line up with the - O degree, Top Dead Center mark (TDC) first. With the Distributor cap off the distributor so you can see the Rotor. The rotor will rotate almost to the front pointing at the back of the throttle body of the EFI. You need to mark the distributor cap , once you get it on ZERO, to mark it as number one, on the post bulge on the cap that the rotor points to. this is the post we start with in putting the wires back on in sequence. This puts the wires back on the cap according to the firing order you see on the intake manifold. The rotation of the rotor you see...as you bump the started over, tells you how the wires...in sequence go around the cap...the firing order from number 1 goes in that direction. Remember on the vehicle ..the odd numbered cylinders are on the drivers side...Number one at the front ..then 3, 5, 7 to the back. All the even cylinders are passanger side 2 at the front ..then 4, 6, 8 in order to the back. You really need to tab the wires at the Cap End... as to which one is which cylinder. Use a piece of masking tape make a flag tab folded around the wire so you can easily see its number. Then run your sequence of firing order puting the wires to the cap in that order. This assumes you still have the wires on the right sparkplug....if you pulled the wires off the Cap and the sparkplugs...its OK..just mark which ones fit to the cylinder...one at a time...and tab it the same number on each end first. Post back if you are lost...tell me what has been removed...and what you left hooked up the same as it was BEFORE you started. It will go back together...and run . If you pulled out the distributor base then we need to talk.
please do rate the solution.

Back fire


the fuel pump or the sparkplugs or both,check it out.
or
Could be in need of a tune up... carb and timming adjustment. New plugs,wires,rotor, dist cap.Tune ups are needed on a regular basis ussualy once a year depending on the amount of miles you put on the car? The charging system sounds o.k but tune up may be in order
or
Timing is way off specs, or plug wires hooked up incorrectly. I would suspect the latter.
Firing order 1-3-7-2-6-5-4-8
or also
if vacuum leak
