engine wont redline?

merryprankster · 06-22-2007, 01:39 AM

when i rev it, the engine starts, i dont know, putting? at around 4-5K rpm. so im afraid to redline it or even go near the redline in fear of breaking something.
help?

sounds kinda like a spark advance problem at revs that high. Or just your ignition timeing is off. check thse first and then tell us what you found. Just start with the easy things like plug wires, plugs. Also make sure the plugs wires arent arcing somewhere when the engine revs up all of these are possiblities. If it turns out to not be spark, have you replaced the fuel filter recently? Bad gas is possible but unlikely. Run the code and see if it has any codes stuck in it.

wow i feel like a noob.
how do i check the ignition timing?
how would i know if the wires are arcing? im planning on getting ngk ix plugs, but thats 40 bucks (O_O)
also, whats the diff between power cables and wire sets?
thanks!
btw, how do i 'run the code'?

You kinds do sound like a noob lol. But ignition timing is easy take off your distributor cap remembering where the number one plug wire comes out from it says it on the cap. Then make sure your car is out of gear and the parking brake is set. On your crank shaft pully look for the timing marks behind the pully on the timing cover. There will be an indentation and a 0 10 20 30 these are your 0 and 10 before TDC 20 and so on. On the pully there will be a little line on the back of the pully close to those marks. Turn it to where it faces the 0 this is your TDC. Look at the rotor button in the distributor it should be pointing towards where the number one plug wire comes out of the cap. If it isnt then you have one of 2 things you are on the exhaust stroke or it is really far out. Also look at the adjustment slide on the side if it looks like you need to go a way to get to 1 but it is maxed out the you need to pull the distributor and move it the correct way one tooth. If all this stuff checks out then it is time to check to see if your cams are lined where they should be. Pull the top timing cover with the crank pully at 0 and look at the cam sprockets there is a prevelent line on the rear part of the timing cover these are your timing marks. On the sprockets you will also see marks these marks should line up if they dont then you are out of time and this would explain your problem. If they check out the you are left up to moveing the distibutor while the car is running and you are shooting a timing light and the mark on the crank, which by the way while you have it at 0 during all of this take some white out and make a mark on the crank pully and the 10 mark this is your spark timing. 10 degrees before. what you do is turn the car on and connect the timing light clamp around the nuber one spark plug wire and the black and red wire from the light in the battery terminals respectivly. and shoot the light towards the marks you made and if the mark is not lined up turn the distributor till it does line up. Also I forgot on the check engine port put a short wire between t and e1 plugs. Thats it for timing if that dont fix it then take off all of your spark plug wires and check them for damage like cracks and stuff like that if you find anything like that replace them.

I wouldnt worry so much about the irudiums they are nice but a good set of bocsh platnum plus fours work good to. I am not sure about the power wire and plug set take that back your power wire is prolly the coil wire and the plug set is the spark plug wires. Just go to auto zone and ask them for the spark plug wire set for your car you are gonna scream when they tell you the price. Remember no crying. But if you dont find any cracks or burn spots in them I wouldnt worry about that unless you are not sure how well the guy that had it before you took care of it.

supradaddy0803 · 06-22-2007, 07:11 PM

Lastly to check codes on your ECU take a jumper wire and on the check engine port under the hood bridge the T and E1 ports in it and then get in the car and turn the key on but dont start it. Count the check engine light flashes it will do a series then a space then another series. like a 2 then a 1 for code 21. if there are any on there post them on here and I will tell you what to look at.

merryprankster · 06-22-2007, 11:02 PM

sounds good. i asked about the iridiums because id like to get an msd or hks twin power system to improve my combustion efficiency.
ill do the check engine think tomorrow, but what do i use for a jumper cable? maybe you could post pics for the distributor, TDC stuff, etc.
ive got a TSRM, but im new at using it. i can prob figure out the engine codes though.
thanks!

supradaddy0803 · 06-23-2007, 04:00 AM

for your jumper just do what I do use a little peice of wire from like speaker wire it fits and all you have to do is short it out. In the TSRM the page you want for checking the codes is FI-27 I had to look it up but with a N/A 7m you will be at that page a lot I am afraid. All the other checks I gave you are in there in the sections like IG for ignition and timing is in the EM section for egine mechanical.
