I have a friend that has an old 84 190 with a 5spd he is about to sell. I am considering purchasing the car. Have any of you guys driven one of these? I never had until today and wow it was fun! I was running about 80 at 2500-2600 rpm and it was just as quiet and husshed as my moms Lexus. I was very impressed.

The car has a rebuilt head, new valves, timing chain and tensioners because the chain broke. He has had it since it was a yr old and it is really in good shape. All maintenance has been done and the car really runs great. I have 2 concerns.....

One is the car cuts out when shifting to second, I mean CUTS OUT, and then comes right back. Just a split second cut out. He thinks it may be the coil. I have no idea.

Second, the oil pressure gauge seems messed up. It has a new oil pump but at idle it sits on dead 0 and at 80 it sits at about 2 1/2. I actually cannot get it to peg out. The motor is super smooth and quiet. That is why I think the gauge is just off.

What do you guys think...

Thanks!

Those oil pressure readings are not acceptable for that engine. If you suspect the gauge is faulty, it is common for the oil pressure sender to fail. You could try either hooking up a mechanical gauge or putting in a new sender unit.

ok, thanks I am sure it is nothing big. It runs so quiet and smooth.

I wonder what is causing the engine to cut out?

Could the coil have anything to do with the cutting out of the engine?

Thanks
