Tps is preset at factory, if a trouble code was retrieved from computer, then replace the TPS, PERIOD............... ANY TYPE OF adjustmt., is done by loosening bolts that hold it in and twisting or turning it one way or another, then retighten bolts, which ever improves the condition, do this with engine running, you'll know which way improves best. I would just replace the tps, and be done.

Testimonial: "Thank you for that last response I did not see that before I realized I had to adjust the tps one way or the other...even driving local I was noticing the rpm up's and down's.... Ihave since adjusted to the right..clockwise and with local driving I don't notice's just when I let off the gas I notice the rpm guage dip then go right back up but nothing like it was before..the real test is when I take it on the highway and get in final gear and put on cruise and get it from there....if it happens at faster speeds I will slightly adjust again and try again..thanks again for the response."

    The other good thing is I had the code cancelled and it has not returned so my highway test will be the final test..thanks

when your vehical throws a code and you replace the defective part, you must clear the code or the ecm will still recognize it as an active code.

SOURCE: Timing my 1998 Mitsubishi Eclipse GST

the timing marks on your crank and cam crank need to be one on top of the other if you understand what i mean. anyway if this is done correctly, your cam should make two revolutions to one of the crank thus after one full revolution of the crankshat gear your camshaft gear should do 2 revolutions and you timing marks should be next to one another

SOURCE: Valve Cover Gaskets on 2000 Mitsubishi Montero Sport

If you are sure you have gotten all the bolts out then you may need to pry up on the lip of the valve cover with a flat blade screwdriver. Take care not to bend the valve cover too much. They sometimes get stuck pretty good. Good luck.

SOURCE: bad valve cover gasket, misfire and tapping lifter.

what do you mean with 'bad valve cover' ?I asume it is leaking means that the rubber seal is not sealing anymore,it has gone hard.tighten the cover bolts sometimes seals it for a get to the rubber seals the inlet manifold has to be unbolted and moved,a fairly involved procedure but easy to do if you have a manual and standard handtools.The misfiring is likely stray arching of the coils .remove the top plastic cover of the motor andlook when it is very dark [like lightsof in your garage] and look for sparking.If so ,replace sparkplugs or/and leads.[remove inlet manifold also]Tapping lifter,works with oil,try engine oil flush and/or change oil brande.if problem persist replace lifter,lifter undervalve cover

99 a4 2.8 audi quattro just put heads on car set timing all timing marks and holes line up ,when turning engine over by hand u can here valves clicking on cam on drivers side not set right ?

i have a 99 audi a4 2.8 quattro i got the car and the timing belt snapped or somthing idk before i got the car but i ended up swapping the heads from a junkyard i had engine code AHA heads which had severe bent valves i did a compresson test and came back bad and swapped them from a vw passat with ATQ heads got all the head gaskets and all gaskets off ebay...the timing belt making sure everything is lined up correctly is crucial if it looks the slightest bit off on the cams you better do it again there tricky the marks for the cams are under the valve covers on the back side of the heads each cam will have a small square notch the should line up perfectly with the lines if they dont somthings not right on the heads on the flywheel/crankshaft pully..idk what its called theres a mark down there too that lines up with the flywheel/crankshaft pulley and plastic cover ..but i remember i lubed all the cams and valves down with oil before i put the the valve covers back on i remember mine tapped a little bit on first start up but it got quieter and quieter within 5 min of ideling ...also make sure you dont have the timing 180 degrees out i guess i got lucky make sure i think #1 is on compression stroke not exaust stroke





if you hear really loud tapping if it were me i know you not gonna wanna hear this but id pull the valve covers again and make sure 100% positive all marks on cams are perfectly lining up if it looks to be off a tooth you possible could have a bad timing chain tensioner on that driver side

I have a 2005 Sorento 3.5 changed out valve cover gaskets and tuned up since I've done this all it does is crank over tries to start but will not start I tore back down to make sure I did not have the plug...

recheck the timing marks if the belt has been changed, the fuel gauge is connected in to the fuel line with a T piece connector, check the pressure and flow, if the flow is low replace the fuel filter , if the pressure is low check the relief value, if ok replace the pump.

2002 Honda Civic ex wont start

After so many over heats.a car sometimes cant handle.
after constant over heating your cars rubber gaskets could have gone bad and turned brittle letting in oil into spark plug well #1
for your spark plug problem i would recommend changing your valve cover gaskets.
and for the over heating and not turning on.
i believe you blew a head gasket.

Lincoln LS wont start

if the belt is moving , the engine is turning over
what you are trying to say is that it is cranking but not starting
I would be checking wire connectors for the cam position sensors , injector wires and any other connection s around the area you have been working
make sure that you have not caught a wire under a cover

Need to replace valve cover gaskets on 1992 camry and howmany are they

Buy the valve cover gasket in one of local auto part stores.
Don't start the car, put it on parking breaks. If you drove before wait when engine cools down. After then you will need a 10 mm wrench (it can have different size). Loose all nuts on the valve cover. After that remove the cover carefully. It's possible that you will have to disconnect and loose more stuff from the valve cover. When you open the cover you will see 4 gaskets for each spark plug place remove them also. Now you will need something to clean surface where the gaskets go. It can be special spray to degrease surface or it can be regular gas. Don't spill any liquid on the engine it can be harmful. You can use also sandpaper of minimum roughness to clean the surfaces. After that put the spark plug gaskets on it's places. If they don't stay there you have to buy special sort of glue (usually it's not a case). Then put the valve cover gasket on it's place, there are special grooves. Install the valve cover gasket extremely careful the valve cover gasket is very fragile. After you putted everything on its places start to tighten. You should do that in certain order. Start from one of the edges then middle opposite side and then the side from which you started but another edge (the same for another side). Don't tighten it comletely for one time, make couple "rounds" before you finish. After you check and connect everything remove all your stuff from the engine compartment and start the engine. Don't close the hood you need see that there is no leakage.
