issues with accelerating

[MATTROBERTS]

Help!

For some reason my 1999 TVR 4.0 doesnt like accelerating all of a sudden. In an instant it will cease all power, usually in first / second with the associated slowing down. I am just learning about cars and find this worrying as I only owned it three weeks. I took off the ECU, no problems there, same detail with the silver relays on the black and blue boxs. I did check the coil and quite a lot of oil came out of the plug, is that normal?

Sorry if I am missing something spectacularly obvious!

Cheers!

Matt

Did you check the fuel pump relays on the big coil of cables running to the ECU?

Oil in the coil sounds worrying. The coil is typically encapsulated in oil so it could be leaking from that, unless the oil is actually from over enthusiastic WD40 usage. Hesitation under load is often an HT related issue, so coil and leads would be high on the list of potential culprits.

justa question on your profile your region is "oberts" where the hell is that?

[MATTROBERTS]

EEERR, supposed to be Hampshire. Not too sure how that ended up there. Will check fuel relay and coil. cheers

fuel relays seem to go about once a year on my chim but about £6 each at your local car spares mine just seems to die, switch ignition off then on when driving and if prob solved, relays

The proper Bosch ones can cost anything up to about £16 depending where you buy, which might seem like a rip-off compared to the prices you're paying, but they usually last a lot longer than a year! might be worth checking that the socket is connecting properly - if there's a poor joint then the relay will get hotter than normal and likely to fail sooner.

Oil coming out of your ignition coil?

Do you have sparks coming from your dipstick?

[MATTROBERTS]

No. sounds painful.

Good point. See a doctor...
