Check intake gasket by spraying carb cleaner around intake and head mating surface if idle changes then a bad gasket is in play. A lean code on bank one or two possibly both should show when computer detects. Does it seem to run good off idle? Also check plugs for proper gap or burnt electrodes.

Engine miss and no codes
i woul tend to look at mecanical part since ecm not setting any codes
check compression check valve lash may be a valve not opening or closing properly (out of adjustment)
all i can think of now


unless your check engine light bulb is burnt should light up when you first turn key on

How do I set the timing on my 1967 Mercury outboard motor? It starts but seems to sound like it has a slight miss, and when you idle down to put it in gear, it dies.


I have seen it done. The shell is removed to the points. A probe is inserted in the cylinder hole for #1. When the piston is clocked to TDC the breaker plate is locked when the piston touchs the probe and provides continuity. Some engines may require a few timing degrees either BTC or ATC. Throw in new points to eliminate the low end miss as weak spark at low rpm may not flow good on worn points.

Relist on outboard motor or boat section of Fixya.

Check intake manifold vacuum with a vacuum gauge. Should be 17-21 inches. Low vacuum 10-15 inches would indicate a bad cat. Or you can remove the oxygen sensor and drive it. If the power is better you have a bad cat. Misfires can melt the cat converter.

Toyota Rav 4 1997 .Check engine comes on .Codes are P0301,302,303,304116 . What to do.


The engine coolant temperature is high. Your other Codes are for missing cylinders on cylinder 1,2,3,and 4. Get the Codes cleared and start over. Changing the plugs and wires,etc could have generated the missing cylinder Codes.

Autozone,Advance, and Oreilys will scan for free.

Check your engine for an IDLE SPEED CONTROL SOLENOID, which may be in the intake. Or a fuel pressure regulator.

A lot of times people work on the spark side and forget the fuel injectors. They can cause a miss.

Had mass senser replaced ran good 4 awhile now running bad again . also when i rev up to 4000 rpm it starts missing


Do you have an after market air intake that uses an oiled filter? If so - you could very well have fouled the MAF sensor again. If not - you could be having a misfire condition - which will throw a code and trigger the SES (Service Engine Soon) light. Any major auto parts store will have an OBDII scanner and will be able to read the code and clear it.

ENGINE MISSING ABOVE 3800 RPM


no the code is most likely from a dpfe sensor for you egr system not the egr valve itself.a clogged fuel filter though might cause your low revs
