While accelerating in low RPM at top gear or going up hills, just tonight my 924 was having a terrible time. The RPMS would stay the same, but the oil pressure would take a hit and the car would jerk or chug.

I run 91-93 octane fuel, my car is a daily driver. It has needed a fuel filter for awhile and the plug wires are probably original (new plugs tho) but I'm on a buget, I want to fix the problems as they come along... any ideas what the problem is?

I think you're thinking right with the wires. Start her up and peek under the hood while it is dark. Once your eyes adjust you might see the arcing - its worked for me. Bruce

Thanks! It missed this morning but not when I drove home. I check it out once it gets dark.

It may also be an injector, my car has a nice diesel like chatter to it.

If the problem was secondary ignition, the oil pressure wouldn't drop. If it was a voltage issue, then I'd think all of the guages would go bonkers. Maybe a oil level or pump pickup issue activation the low oil pressure safety switch? This would also fit acceleration/uphill as rearward slosh could interrupt pump supply.

I'm not that familier with 924's so if this doesn't fit, maybe someone can correct?

Good luck,
Bill

Very true, I have had problems in the past with my oil pressure taking a longtime (10-20 seconds) to build up. i wouldn't be suprised if that is an issue.

When I had the car up on the jack and started it on the new oil change today, it worked as it should (built almost immediately even with a dry filter).

However, the front of the car was elevated and the front is also elevated when going up hills.

As far as 944's and 924's, they had identical engines I believe...

944's and 924S's(86-88)have the same engines, not regular 924's(pre 86)
