I need some help here!!!!!
Okay everyone I've been having some problems with my old car that I use on rainy days when I don't want to get my out of the garage. It's a 1990 Beretta with a 3.1 engine. It's been running rough at idle and sometimes stalls after I start it. If I drive it kinda easy it seems to run smooth most of the time. If I kick it down at around 45 or 50 it boggs down like turning the engine off until you let up on it. It acts like its running out of fuel. The car has about 165,000 on it so its starting to wear out I'm afraid. I thought it might be the fuel pump so I had one put in Friday and its still doing the same thing. The low coolant light flashed on a couple of times, but no check engine light. I noticed the other day that the charging needle was pretty high on the gauge. Here's what I found today while looking around under the hood. The ground strap that attaches from the back of the engine to the firewall is broken and not attached to the firewall. Do you think that I might have found my problem? Thanks for your help.
I own a Jaguar which are notorious electrical demons. This sounds like problems I had with mine when a wire comes loose or the battery is starting to go. When the battery headed south on the Jag it would do all kinds of crazy electrical things like tell the car it was running to hot and put it in to limp mode. Im no expert by any means but sounds familiar to electrical problems I had had.
Check the MAF connector and sensor. It might also be a bad connection on the MAP sensor. My mother-in-law has a 1991 Lumina with the same engine and we have had to do a little "doctoring" of the system. We had a badly gunked-up couple of sensors that were causing rough idle. We also had problems with the torque converter lockup solenoid.
Good luck,
Mike

I put a converter lockup solenoid on about 10 months ago. I'll look at the MAF and the MAP sensor. I did find out the battery was low, so I put a 24 hr charge on it but have'nt driven it yet. I was hoping that a low battery could cause it to not run good. Thanks for your ideas.

Did you change the fuel filter too?
How old are your spark plug wires?
The plugs and wires have about 6,000 miles on them, I pulled one yesterday and it looks brand new. The fuel filter is three months old. I've checked the grounds, I just put a charge on the battery yesterday.
