RE: problems while accelerating
Sounds like a fuel problem, may want to check all electrical connections to the fuel pump, looking for corrosion or loose connections that could be dropping the voltage to the pump. Your 3.4 does not use a MAF, the MAP runs the show, so check the electrical and vacuum connections to the MAP sensor.

RE: problems while accelerating
maybe a stupid question but is there a specific part "fuel pressure regulator" in V6 3,4? I cannot find it neither in haynes nor on ebay...

RE: problems while accelerating
The fuel pressure regulator on the 3.4 is part of the fuel injection rack, and according to the FSM it must be replaced as a unit with the fuel rack. However, after market rebuilding kits are available from many part stores.

I am just throwing out a guess here, but wasn't there a sensor that measured how much throttle is opened? TPS I think? Could it be a malfunction in the TPS that results inthe sending of improper data on how wide the throttle is opened to the PCM?

RE: problems while accelerating
yea there is the trottle position sensor and the idle air control valve
the IAC valve control the air and fuel mixture
currently i was having problems accelerating and driving period i was getting a misfire and a bad shaking
took it and got it scanned and found out my IAC valve motor had went out so i have to get that replaced and engine coolant temperature sensor and that should stop the acceleration and misfire problem
does ur car idle high?

RE: problems while accelerating
yes, it idles showly higher than it should (at about 1000-1100 rpm) and certainly it does not "hold" idle - the rpms always seem to go up and down a little...

RE: problems while accelerating
thanks. and can this have affect on the issues i have described?
problems with idle are something that I could live with for some time, but the rest just makes my car useless...

RE: problems while accelerating
aw well i guess the engine coolant temperature sensor is causing my misfire and insufficient fuel suppliage
