Anyone in the Hull/East Yorkshire area with a '98 - '05 GS300?

[Chris CPT]

Hi guys.

I bought a 1998 GS300 a couple of months back cheaply as a kind of project. Was running great, but needed a couple of tyres, cleaning inside plus a good polish and wax. Other than that it's a good car.

However, it recently started 'chugging'/running rough at idle, plus hesitating as you rev it, or try to accelerate. The problem comes and goes. There are no warning lights on the dash. Checked spark plugs and coil packs and all are okay. 

After lots of research, it seems very likely that it's the oil control valve (OCV). I took it out, cleaned it and the little mesh filter, but the same problem happened soon after. 

Anyway, it's a main dealer only part; Toyota/Lexus both quoting £130 mark. . Before I go splashing that much cash out, I want to make sure it is actually the OCV. 

Does anyone in the Hull/East Yorkshire area own a 1998 - 2005 GS300 who would be willing to let me test their OCV in my car to see if the problem disappears? It takes literally 5 minutes to remove/replace the OCV. 

Thanks all, Chris.
