Hello it sounds like you might have a bad map sensor the smell your smelling is raw fuel being dumped and being burned in the exhaust test the map sensor to see if it within range ,if it checks out okay check your iac motor idle air control valve if the pintle gets stuck in the bore it will cause stumbling ,hesitation,even no start conditions,goodluck please rate
hello again you should be able to this your self if its a factory one it should just install aftermarkets usaully have a different design usally comes with different size orfice washers they have different numbers marked on them you will have to match up oem numbers to paper they give install the washer it calls for goodluck please ratehello again you should be able to this your self if its a factory one it should just install aftermarkets usaully have a different design usally comes with different size orfice washers they have different numbers marked on them you will have to match up oem numbers to paper they give install the washer it calls for goodluck please rate
hello look at the valve cover the gasket probley is leaking and its collecting in the plug ports goodluck please ratehello look at the valve cover the gasket probley is leaking and its collecting in the plug ports goodluck please rate

no miles stated, 400k miles> or 100 = 100k?
if any 95 has 100k miles that be like a new car. no ?
5k /year, wow...
trouble is i cant drive car. and see this effect.
the issue is acceleration, right? :called Hesitations !
and only happens on a hot engine , yes?
and never happens wide open throttle.? correct? HAPPENS: only when tipping in the throttle at cruise. (then self corrects )
THE TPS sensors does that.
The TPS is a demand sensor. it sees driver DEMAND
acceleration, and this is detected and the PCM goes to ENRICH mode. this is done or the engine goes LEAN until the MAP BARO READINGS, catch up and correct fueling.
that is my wild useless guess. (not driven and me not scanning the PCM while it fails.)
The TPS is a rate of change sensor.
This is because all air meters made are slow.
The TPS hides this fact. until bad.
there are other causes,but im not there with my scan tool..
and (box of gauges)
IF WHAT YOU SMELL IS RAW GAS THAT IS AN URGENT PROBLEM THAT SHOULD NOT BE PASSED OVER. IF YOU SMELL A ROTTEN EGG SMELL THEN YOU MIGHT HAVE A CATALYTIC CONVERTER PROBLEM THAT GIVES POOR ACCELERATION. CHECK FOR FUEL LEAKS AND CHECK FOR ENGINE VACUUM AT IDLE. MUST BE AT LEAST 19 INCHES,. IF NOT, YOUR CONVERTER IS PLUGGED.
Basically this means that the the car's computer has detected that not all
of the engine's cylinders are firing properly.
A P0300 diagnostic code indicates a random or multiple misfire. If the last digit
is a number other than zero, it corresponds to the cylinder number that is misfiring.
A P0302 code, for example, would tell you cylinder number two is misfiring.
Unfortunately, a P0300 doesn't tell you specifically which cylinder(s) is/are
mis-firing, nor why.
Symptoms
Symptoms may include:
the engine may be harder to start
the engine may stumble / stumble, and/or hesitate
other symptoms may also be present
Causes
A code P0300 may mean that one or more of the following has happened:
Faulty spark plugs or wires
Faulty coil (pack)
Faulty oxygen sensor(s)
Faulty fuel injector(s)
Burned exhaust valve
Faulty catalytic converter(s)
Stuck/blocked EGR valve / passages
Faulty camshaft position sensor (more than likely your culprit)
Defective computer
Possible Solutions
If there are no symptoms, the simplest thing to do is to reset the code and
see if it comes back.
If there are symptoms such as the engine is stumbling or hesitating, check
all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending
on how long the ignition components have been in the car, it may be a good
idea to replace them as part of your regular maintenance schedule. I would
suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable).
Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic
converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter
needs to be replaced. I've also heard in other cases the problems were faulty
fuel injectors.
Random misfires that jump around from one cylinder to another (read: P030x
codes) also will set a P0300 code. The underlying cause is often
a lean fuel
condition,
which may be due to a vacuum leak in the intake manifold or unmetered air getting
past the airflow sensor, or an EGR valve that is stuck
For the car reving itself, it could be the throttle positon sensor (i dont know much about it). I've experianced this myself but it comes and goes. Usually allowing the car to reach normal temp before driving properly helps this.
As for the egg smell. It will most likely be something to do with your fuel/petrol. Your engine wont burning sulfur properly and then turning it into hydrogen sulfide which is supposed to smell like eggs.
A good service should fix this, oil change, air filter, oil filter etc.
usually ,when using the egg discription it referred to as a rotten egg smell ,not burnt.. if this is the case you may have a catalytic converter that is in need of replacement..
you probaly have a small pin hole in the evap system somewhere. Mechanics usually wont try to fix this problem because its a pain in rear end to locate the leak. This problem should not effect the performance of the car
That rotten egg smell is a problem with your catalytic converter. Too much back pressure is not allowing your engine to run normally.
I'll bet its been getting hot too.
Warning: For your own safety, until this is resolved, do not look under or stick your head under the car with the engine running. I've been in a vehicle when a converter with these same symptoms blew apart at the seam. Made my head hit the roof. If it happened a few minutes earlier I would've gotten a faceful of freshly flattened converter. So be careful.
To tell for sure about the problem, try to get it to an auto parts store that does free code readings from your On Board Diagnostics. There should be errors referencing the engine, O2 sensors and emissions. The exact diagnostic codes with determine your next course of action.
egr valve flow problem can i fix it or is replacement inevitable
i changed my plugs yesterday and there was oil dripping off them do you know why?
