OT mechanics question

Was it shaking or running as normal? How many miles on the vehicle? Is it a daily driver? Are you OT rich? Alot goes into determining if the cost to repair a vehicle is worth it.

Not familiar with that particular vehicle but you could start with just changing the plugs and coils yourself if they are easily accessible. Ive done it on one of my vehicles and it isnt hard.

If you are at all mechanically inclined, look up changing plugs and coils on the tube. Can probably find a video on it. I would start there. Actually, would start with the plugs first. Could be an easy fix.

Plugs & coils are easy, intake manifold gasket isn't.

Apparently coils aren’t cheap.

I wouldn't think they'd be over $200 for the coils

Nissan OEM coils from dealer $100-150 each. Rock Auto Hitachi or Denso coils are $40ish each. You could save some money going to an independent shop.

I would go decent aftermarket and skip the OEM $.

Also, invest in a code reader. First time you use it, it'll pay for itself.

I have the BlueDriver OBDII Scan Tool, paid $99 for it and it is bluetoothed to your phone. Super easy to use, gives the code, most likely repairs to least likely, links to parts. It's really idiot proof and the first sensor you replace on your own, you pay for it. Works on every car past '96.

2010 Nissan Sentra

Service engine light started flashing.
Wife drove about 5 miles to shop and dropped off. Maybe less than 5 miles. Not more for sure. Shop estimate 1200.00 repair needed to replace plugs and coils. Saying 2 coils melted. Also replacing intake manifold gasket. I trust this shop and have always felt repair costs have been fair.

Does this repair cost sound fair? Would appreciate some feedback.

The joys of accessing coil over plug coils on a transverse-mounted engine.

Price is probably spot on for a shop around $125 an hour.

You have to take off a lot of stuff including the intake plenum (the reasons for the gasket) to get to the cylinder bank that is against the firewall.

Someone mechanically inclined and having the tools can do the job in under 3 hours taking their time. Parts price depending on the brand of the coils is probably $700-800.

The parts bought from one of the major online parts houses would be more like $300 for quality ones like Denso.

Do not let them put cheap no-name coils in it. I have seen a ton of them go back and it always seems to be on the back bank. You can change any one of the three on the front bank in under 10 minutes.


ETA if by chance you try to youtube and DIY get a set of the wire connectors that attach to the coil before starting the project along with the other parts. On a car that old the current ones may disintegrate in your hands. You can usually find them for 15-20 bucks on Amazon or eBay. The connectors usually come with 5-6 inches of wire on them do NOT cut and splice your wires! The connector will disassemble and you can click the old wires right into the connector and reassemble it. They are all different but it usually requires taking off a cover then pushing down a little tab next to the wire to release them, the wires on the car will them click into place.

That sounds like a fair price to do the work you mentioned. Whether the work is needed, I can’t tell without more info.
