I've got a 1.8 block and 40m and 16 cillenderhead what can it be

Ok just spent hours checking parts and found the culprit to this code in my 1996 Hyundai elantra.

Micro fissure cracks in the ceramic of the spark plug. This was noticed while cleaning the plugs. Changed plugs and still had a misfire and code.

Little more testin of cylinder compression, IAC cleaning and checking, ignition block testing, fuel filter check, fuel pump filter check, plug wire check, spark plug gap anf cleaning and checking, and was in in the process of getting ready to remove catalytic converter when I had a thought all this could be some simple vacume leak. Checked PVC valve.

Well what do you know bad PVC, changed it and the car runs great.

So over cap code P304 Cylinder misfire - CHECK YOUR PVC VALVE!

I felt like an idiot after spending 5 hours tearing everything down and testing and was at wits end and about to pull the cat.

Everytime you drive the vehicle it starts jerking and wont pick up any speed.They say its the fuel pump staying on or either it need a gas line.Nobody seems to know whats wrong.

i got the code po455 when i did the oil and oil filter and air filter what can i do to stop the smell

runs now but revvs up and down goes all the way to 2000 rpm by itself what could be the problem

ex stole key and uncle took out battery to keep from being taken when i wasnt home...we got the key back and put battery in but now alarm goes off when open doors or try to start car...lites and diffrent sound to alarm go off...how can i stop this...does not have power locks so the lock unlock button dont work. can not find a kill switch or button under dash.

My car behaves normally when cold. After it has warmed up, if it is shifted out of drive and then back, it will not engage. Also it will not hold reverse when it is warm, but will when cold. When I got the car, it backed itself onto my trailer for the trip home with no trouble. I never have problems starting the car, and it will only start in park or neutral. Could this be the neutral safety switch or is it an internal problem? I am not getting any diagnostic codes, and the MIL never comes on when the problem happens.

my car started spuddering an the check engine lite was flashin then we parked it for about 2hrs when we went out to start it it would not start it cranked an attempted to want to start but failed then after i had it towed home i tryed to start it 2 days later an it wont start it is also not poppin or attemting to start it cranks normally but i replaced the throttle position sensor an the crank sensor but still no luck i have gas coming to the fuel filter an a strong oder of gas after attemting to start it i also took out the spark plugs an tested them by groundin them to the frame an cranking it a couple of times all appear to have spark one seems a little weaker than the others but car still wont start is there a way i can test the ignition coil packs for resistance

HOW MUCH DOES A TRANSMISSION VALVE BODY COST? AND WHERE CAN I GET ONE?

HOW MUCH DOES A TRANSMISSION VALVE BODY COST? AND WHERE CAN I GET ONE?

The Valve Body has a crack ln one of the corners. Would that cause it to lose pressure and keep the overdrive from engaging?

THE PLATE THAT THE FILTER SCREWS ON TO, IS THAT A PRESSURE PLATE?

I just changed the starter when I drive now the transmission drops into a lowgear and almost making the car stop What could it be

Fuel pump ok, new plugs and wire, new starter...no spark coming from distributor..engine turning over fine but will not start
