Hi All,

Thought I'd share this, as me and my SE are about to renew our vows.

I've had my '90 SE for nearly 2 1/2 years now and pretty much enjoyed every minute of ownership.

Yeh, it's a 90's car (of 70's design) with 83k miles on it so, I've always forgiven the engine for being a little......well...........less than silky smooth at times.

I had a slight flat spot when pulling off the line, also evident if the throttle was blipped while idling, and the cold start and warm up period was pretty smelly.

Even when warmed up, the exhaust smell was still strong. It's got the de-CAT conversion so I didn't worry.

Then, along came trouble. A new level of lumpiness, a soft misfire and a drive that wasn't at all nice. Something had gone wrong.

I removed the Rochester injectors and ran them through the injector testing/cleaning rig.

One of the injectors was 9% down on flow rate and strangely, one was about 2% up. The other two were normal as per my previous injector testing/cleaning session a year or so earlier.

I ran them through the cleaning process but couldn't get them on spec.

They all still measured 2.0 - 2.1 ohms across the terminals and the spray patterns were still good (for a Rochester)

I nervously decided it was time to part with a lump of cash and ordered a set of RC Engineering PL2-370 injectors from Fuel Performance Ltd. £403.99 inc vat and delivery.

They came next day even though I'd selected the 2-4 day delivery option which was nice.

Checked the resistance reading across the terminals, pleased see they were all 2.1 ohms.

Fitted them without issue. Yes, they are a few millimetres shorter than the original Rochester but the O rings are still still well inserted into the fuel rail and inlet manifold.

And what a difference from the moment i turned the key.

The engine now idles and drives so smoothly, it's a revelation.

The flat spot has completely disappeared when i pull off.

The idle is now a soft purr rather than a throbby (sporty?) chug.

And no more fumes from the exhaust. Yes, it doesn't smell as sweet as a CAT car but the pungency has gone.

It feels cleaner and more lively in the lower rev ranges but mid to high range and ultimate acceleration experience is probably the same.

If you're Rochesters have over 50k to 60k miles on them, I reckon you'll see a huge difference with the RC's.

 

Cheers, for now.

Andy.

 

 

Reassuring to see another positive review of these injectors

Now I've started using my Esprit more I've observed a bit of a flatspot when I pull away too and have a set of these on order too at present. Looking forward to them getting here to see what difference they make to my car.

I have installed RC-s in 2017, they are Awesome !

You can save a bundle by ordering injectors directly from the manufacturer, no VAT,
