I have a 92 740 wagon runs rough.when driving for a while (50 miles) you start smelling gas in the car.took out a spark plug smells like gas color is good on the plug.did the obd the only code I got was 232 lambda control fuel to rich or lean.so what doyou guys suggest 02 sensor no good fuel reg needs changing,or a bad injector,did the screwdriver to ear test and all injectors are clicking away.thanks in advanced for the help.Chris

The fuel pressure regulator may be failing. Pull the vacuum hose off of it and see if any fuel leaks out. If it leaks fuel out of the vacuum port then the internal diaphragm is shot.

If it's a non-turbo with Regina fuel system, an O2 sensor failure would be unlikely.

thanks chris that was it spitting fuel all over now heres the thing my ignition is regina and emmisions is regina but i orderd a regina fuel reg through fcp and got nothing thats close to whats on the car when i sent there tech a pic he said its a bosch fuel pressure reg what the hell is that would you know thanks alot man for the help

I think you're saying you got a Bosch FPR when you ordered a Regina?

If so, the guy at FCP was trying to save you some $$ (maybe). Because the Bosch FPR works fine in the Regina system, and many here have used it in place of the Regina one. (Both systems have the same overall specs, including fuel pressure.)

no no i got a regina fpr it cost $120 was willing to pay to fix the problem thanks for the help will keep fighting tommorrow to fix her ill let you know what it is thanks again man

are the regina fuel systems more of a hassle to repair? I am thinking about a 92' 740 wagon and if it's not Regina, should I still consider buying it? I have read the Regina Volvos are decent.

I've had good luck with a Regina 940 and 740; maybe a little less trouble than with my 240 with Bosch. Seems like I read that a 92 740 non-turbo would probably be a Regina car.

I'd pay more attention to other things like rust, suspension, motor mounts, repair records, etc. when deciding whether to buy the 92 740.
