Car Forum / Nissan / Nissan Cars / March 20061993 Nissan Primera spark plugs
All manuals refer to plugs changing beween june 1993 and earlier and june 1993 onwards. So i don't actually know what type of plugs to use. Nissan Uk recommend Champion plugs. Most suppliers have NGK. > All manuals refer to plugs changing beween june 1993 and earlier and june > 1993 onwards. So i don't actually know what type of plugs to use. Nissan > Uk recommend Champion plugs. You're kidding right? > Most suppliers have NGK. Which is what you should use.  SignatureSteve http://www.atlantaracing.com K reg nissan 2.0 slx. Currently using NGK BKR5EY but BKR6EY also a possibility depending on pre june or post june 93. >> All manuals refer to plugs changing beween june 1993 and earlier and june >> 1993 onwards.

Well it says here in this Haines manual use Champion Plugs, for single point injection models RC9MCC and for multi-point RC7YCC. So you're right there. The two types you mention are the NGK ones for the two engines... so... Look at http://www.ngk.co.uk/ and there's a "Part Finder" button. You can tell it you want a Nissan, Primera, year, engine and Lo! it tells you what plug to fit. I imagine the dealer has the same info on paper. Andy same dilemma as before is it bkr5ey or 6ey. How do i determine whether i have multipoint injection or not? >> K reg nissan 2.0 slx. It probably won't make any difference whether you use BKR5EY or BKR6EY. I use the 6's because they're colder and I've advanced the timing. I've done this on a '94 2.0 for 5 yrs and a '97 2.0 for 2 yrs with no problems. The only time I had problems was a couple of thousand miles after fitting Bosch plugs with hesitation on light throttle. Oh, and the Nissan main dealer had fitted Champions when I bought the '97 which seemed OK until I changed them for NGKs a few hundred miles later and noticed a small improvement in responsiveness. I couldn't get the BKR6EY's the last two changes and have been using V-groove BKR6E plugs with no problems. I've been to several independent garages and asked about tune ups and they all say the same thing, can't. With my old mini i used to adjust the gaps of the spark plugs with a feeler gauge. The timing was checked with a stroboscope. They keep saying its all handled by engine management now but why would it be bad at cold starting? Especially as it starts fine for a minute then runs rough until warm. If it was a normal carb engine i'd say the auto choke was lifting up too early. As for fuel injection i don't know. By the way a while ago a whole load of glass fibre came out of the exhaust. Some say its the muffler some say its the cat. The cat is made from platinum but the muffler is probably some sort of wadding such as glass fibre. Anyhow since i finally got all that clear from the back the car has run faster and i went from 20mpg to 25. I wonder if after a few thousand miles the engine management has detected the change in emissions and this has somehow affected the timing or mixture or something? > It probably won't make any difference whether you use BKR5EY or BKR6EY.

You definitely CAN change the timing on older Primeras but have to do it the correct way (with a strobe) for the engine management to accept it as legit. There's plenty of info around for the SR20DE engine, try http://www.se-r.net/engine/about_timing.html It's unlikely to fix your problem though. You can reset the engine management on a 93 just by disconnecting the battery for 12 hours, that lets it begin relearning. Your problem could be the exhaust clogged, a temperature sensor telling lies to the ECU, a clogged up throttle body, HT leads (only use Nissan's), one of the emissions control valves stuck, again there's info on such SR20DE matters on the site above and others. > same dilemma as before is it bkr5ey or 6ey.

If you drive it hard or for extended periods at higher speeds, use the 6's. SignatureSteve http://www.atlantaracing.com > same dilemma as before is it bkr5ey or 6ey. How do i determine whether i > have multipoint injection or not? Count the injectors? Alternatively, look around for something saying SR20Di (single point) or SR20DE or SR20De (multipoint). And if you find GA16DS or GA16DE, you've been sold a pup. They are the 1.6 engines. It'll say in the owners handbook, if you have one, and may well be on the ID plate under the bonnet.

Get a factory manual. > BTW How much is the official Nissan manual set? How much did the car cost? People pay $20,000 USD for a car then bitch about paying $100 for a manual to know how to service it!

People pay $20,000 USD for a car then bitch about > paying $100 for a manual to know how to service it! $100 for a service manual versus $208 for changing my spark plugs at the dealership sounds like a good trade. Then again, I can't even see my spark plugs or any connecting wires on the V6 3500 in my '01 Pathfinder. Maybe that $130 labor is worth it. In the 70's and 80's I could fix anything on my vehicle. Now I don't even know what I'm looking at. BTW, I drove a 1985 Toyota pickup into the ground at 268,000 miles.(traded out 3 weeks ago (they "gave" me $500 for trade-in value. I attribute that to the amount of beer cans in the back.)) It had an oil leak that wouldn't quit. Kept destroying $165 alternators. I had to get something newer. I'm at a complete loss now if anything goes wrong.

Working on your car is still relatively easy, but now it is also far from obvious. On your 01 pathfinder, removing the big plastic shroud that is labelled something like 3500 V6 or 3.5 etc, will reveal the spark plugs and wires. Without the factory manual, you can figure it out and most probably break it while removing it. No problem. It's just a cover with no function other than making the engine bay look pretty and to hide the inner workings of the motor. If you had the factory manual you would know how to remove it without breaking it. CD |
