Hi

Please help!

Would love to have your opinions on this problem I am having..

Was away for a week just there and after gettin bak jumped in the Rex for a spin, took a few minutes to start (usually first turn) and then ran very lumpy for a while. Also car lost all power under light throttle a few times, felt like i had hit the brakes!!!

Once warmed up it seemed ok.

Later that day went out to do a bit of festive shopping and noticed that the digital mileage display was blank, backlight was on but no digits... and car started cutting out when i hit 2550rpm and when it reached 3600rpm, after a while the digits re-appeared and car ran normal.... exact same happened on way to work and back!!!! when the display works, the cars works????/

The car is standard, 65000miles and has been running not too bad recently... please would appreciate any ideas!!!

its a 1993, standard ecu...

Craig

Sounds like a possible earthing problem mate, also could be your batterys not charging properly or not holding charge, time to get out the multimeter I think.
