Your EGR valve is not closing correctly because of carbon built-up.

======

Check for

vacuum leaks on intake manifold,

the air tube between the air filter.

intake manifold vacuum hose.

===
clean throttle plate with Berryman carburator cleaner

SEE sample picture HERE
===

Also remove carbon built up behind the EGR valve and the EGR passage tube.

===

Vacuum leak WILL offset the intended 14.7 to 1 air fuel ratio.

More un-metered air (leaks) will lean out the fuel mixture.

Use small amount of Berryman carb clearer at potential air leak area will help you identify trouble spot.

At idle,just spray and listen for the RPM surge.

The in-rush of carb clearer will increase the RPM on the motor.

Record the problem spot(s) and address it later.

===

EGR carbon built up require 2+ hours to clean from start to finish.

You will need a new EGR base gasket before your start.

Locate and remove the EGR valve after the vehicle is cool down.

Carefully record the connector and vacuum line (for older vehicle) location by drawing an easily to follow diagram.

Remove the EGR valve.

Inspect the location of the carbon built-up inside the valve and the EGR passage tube.

SOAK these areas with WD-40 spary.

You will need a small screwdriver,cloth hanger and lot of newspaper and time to get this cleaning done right.

RE-SOAK the carbon and let it sit for over-night will also help.

One the last round,pass a shop vacuum of the EGR valve and the passage pipe.

Install the new EGR gasket and connectors.

Allow the vehicle to warm up outdoor to burn up any remaining WD-40.


Take it for a test drive.

You have a leak on your EGR system disconnected the vacuum hose going to the EGR valve and plug it up that will stop the EGR valve from opening and leaking air in to the intake manifold. or you can locate the leak and fixed but in a old truck the EGR sistem wont make mush difrence. keep on mind the EGR system is just for emission control and do nothing to the engine performace. your truck will work fine whit out it.
NOTE: this will not work in newer vehicles bacase will cose the MIL light to come out and fail inspections.

Fast idle cold to hot


to fast hot and too fast cold that it?
well here is normal, its a G16 engine, a Vitara with Sidekick badge.
G16 in cold weather, start and race idle at about 1500 rpm
or more if in ALASKA, you never said that or how cold it is.
the IAC valve is thermal, it and opens more colder, a fact.
the 8valve engine (black steel top) is faster. cold idle
then drops in a few seconds, to 1500rpm
at this time, the ECU brain does NOT control idle speeds at all.
the the engine warms up by virtue of the thermostat
as it warms to 150F to on way to 180f stock temp.
the ECU then takes control of the idle speeds.
got that so far?
so at 180f the idle is 800 rpm (800 is hard coded in the ECU,
ad ECU regulates this, unless you turn on the A.C , and if that happens 1000rpm is called up.
if not the ECU cant control it or the ECU is in limphome mode or worse.

if you insert the diagnostic jumper
does the CEL lamp flash 12s
it must.
see this paper clip this is your only scan tool.
it is crude but that is all you get until 1996.

92 Honda Accord, 5 speed, hard shifting into first & second gear.


First thing to do,try to pump your clutch before you shift into 1st gear then if you feel makes better, most probably you have problem with your hydraulic clutch system, check the clutch line if there is an evidence of fluid leaking or it could be internal leak.

Second thing to do, check your transmission oil, may be it' s too old or you use a thick oil thats why when cold its hard to shift then when the engine rich the normal temperature(warm) the oil become thin and the shifting will smooth. Remember the very old oil become thicken and the purity is gone and can cause of hard shifting. in this regards i suggest you to change the transmission oil and check the used oil if there is small peace of metals, then you are in big trouble,

88 toyota has little power when gas is pressed


your engine seems to be running rich. that may be do to a bad spark plug, spark plug wire, bad distributor cap. If you have a 22re you should check for trouble codes by jumping TE1 and E1.

You should also check your engine timing. With a timing light. The timing marks are located on or above the oil pump. keep in mind in order to get timing right you must have TE1 and E1 jumped. Set to 5 degrees advanced. If your engine is improperly timed it will accelerate slowly, and get worse mileage.

Also adjust/Check engine valves appropriately. they will cause low power.

Also does it misfire at idle?
