Coughing, jumping, engine check light flashing, loss of power

Could check idle control valve / stepper motor .There was a problem on some with dry joints on the throtle body wiring .

check battery cables are tight first, then check earth wires coming from top of engine near distributor are intact and tight and not broken !!!!

as a follow up to previous post i had a weird ignition related problem on this car it would start fine, run, rev, all good ,then without warning jerk, cut out,and lose power, and the cause was a broken earth wire from the throttle body to the inlet manifold if yours is doing the same dont bother with the broken wire ,get a piece of multistrand 0.75 wire about 1 metre long , attach an m6 ring crimp to both ends fit one end under bolt at throttle body end and the other end to the earths on TOP of the engine located just to the rear and left of the distributor cap (remove airbox assembly first)finally, check main earth wire which is fitted to top of engine as mentioned, and goes to right hand chassis rail and is retained there by an m6 screw replace if weak or broken regards j r
