Mein Auto: 325i
1993 bmw 325i bogs down after starting

I have a 93 325I and I really need some help. This my problem, I can start the car up when it is cold and it will idle for a about a minute then will bog down, I can pump the gas and it will barely stay running. I can turn the car off then back on and it will repeat the process only it starts bogging down in like ten seconds. The same thing happens it I drive it. I can drive it about 30ft and it bogs down, I can turn it off then on again and drive another 30ft. that is how I got it home and it was a long drive. What is my problem? I have heard that the Mass Aitflow Sensor is bad but, that thing was like 500.00 at Advance Auto. Can I test it with a meter? and I guess the BIGGEST QUESTION is do you thing that is the problem? If not then what can I check?

Wrong section, you belong in the e36 section.

This e30 is now being parted out. NO body panels are for sale, bumpers/fenders/hood/mirrors/valance or front turn signals. Everything else is up for grabs. Euro grills/cluster are sold, suspension/brakes/LSD/rear tails are already spoken for.

Mein Auto: 325i
95 325i

I have a 95325i with a 6cyl. It has recently started missing. When I start out in first gear it wants to bog down but when it gets up to speed it smooths out. If I am not careful when I start off it will cut off when I start out in 1st. Gear. I have checked the plugs and wires and they appear to be working. Any ideas what the problem is?

Welcome to Bimmerfest! I've moved your questions over to the E36 3 series forum. You'll get help from other E36 owners here and be sure to search around for others that might have had similar problems.

Good luck,

Sounds like you have a massive vacuum leak somewhere. It's running extremely lean, and cracking the throttle open only makes it worst. Certainly you can clean the MAF (do you know where it is and how to clean it? MAF cleaner ONLY!) but you need to examine the intake boot between the MAF and the throttle body, and all the vacuum hoses first.

I also have a 93 325i, had the same problem.. I ended up finding a few vacuum leaks, cleanded the MAF sensor and intake boot. Also had to replace the TPS.. Now she fires up and runs strong Hope this helps!

Clean ICV
Check for vacuum leaks (ICV too)
Check the hoses that are plumbed into the boot on intake

If you have any brittle, dry, cracking rubber.. REPLACE IT.

Disconnect, clean, lube, and reconnect all associated electrical connections.

And, get yourself some TOP TIER PETROL. 91 octane or better.
