SOURCE: acceleration hesitation

Depends how long since your last tune up and mileage. I would do a normal oil change, oil filter, air filter and plugs. If she still does it, try checking for a vacuum leak. Start the vehicle and spray "lightly" carb cleaner around your vacuum lines. If you have a leak the engine will increase in idle suddenly. Replace the line or part. AS A LAST resort and pretty rare is the distibutor. They usually run about 75.00 to 110.00...hope this helps.

SOURCE: Backfires in manifold on motor on acceleration. runs ok low speeds

Nornally reson for backfire is when intake Valve open Internal combustion in Cylinder. Pls Check Your Ignition Timing & Valve Timing. ( I think Your Timing Advancer is Defect )

Its a 1995 eclipse gs. Cranks but doesnt start. The fuel pump kicks in and fuel rail has gas flowing. Its just backfires and sounds bad in general. Ive had several people look at it and no one can so


There are few possibilities that cause such problems.
No start problem,backfire issues.
I suggest you few help links related to these issues.

Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.


To confirm the problem, the basic troubleshooting is required.

Hesitating on acceleration, also backfiring when taking your foot off the accelerator,approaching a junction.sometimes it will just cut out. if i turn the ignition off and restart it will be ok for about a...


Sounds like a vacuum leak in the motor. Backfiring may be its own problem altogether. Backfiring only occurs when cold air is being introduced into a hot exhaust stream or when the timing is off. Check for vacuum leaks under the hood and leaks in your exhaust. If you have a leak in your exhaust it could be interfearing with your emission sensors and giving your motor false information.

Backfire into intake


I'ts quite possible that your distributor is installed one tooth off and is too far advanced, causing the plug to fire before the intake valves are closed completely. Turn it one tooth counter-clockwise and try it again.
